we all get sucked into a pile of "interesting stuff" from time to time - I bid on and won this e-bay auction: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=190034302694 (the link is there if you want to see a photo) - the pile was described as: "a random mix of metal tools.

the stuff arrived today - the "drafting tools" were some cheap dividers - no gloat the metal scribe is a trammel type tool made by General - usable, but no gloat the ruler was Starrett, hardened, cleaned up nicely - no gloat, but at least I'm close to even with that the other "6 inch rule" cleaned up OK, but it has no name on it, is pretty old though - no gloat the aluminum pliers are cute - wonder what they are for - anyone have a clue? the "drill sizer" is the item of great interest - it's not a sizer, it has nothing to do with drills, it's a watchmaker's thread plate made by PS Stubs, of the type described here: http://www.davistownmuseum.org/bioStubs.htm, it's a #61 (or 19?) in pretty good condition, screw sizes from about #4 to someting really tiny, total length is 5.6 inches from the tip of the handle to the end of the screwplate - very nicely hardened too - no idea what I'll use it for, but it's cool - is this a major gloat or a femto-gloat? any opinions?
oh, the "micrometer part" is really part of some optical device (anyone have a clue?) it has a dial graduated from infiinty to 0.5 meters, has a 0.275 inch diameter mounting pin, and two mirrors - it may be part of a camera range/viewfinder? or maybe part of a transit? I'd like to figure out what this is, but it's probably not a valuable or useful item once I figure it out - it's the thing with the round dial in the photo. it is plated brass, aprox square in cross section (.433 inches), 2.440 inches long - the side with the dial has one window (the thing wth the concentric circles).178 inches in diameter, the other side has two such windows, one in line with the window visible in the photo, one at the oposite end of the device - rotating the mirror changes the mirror angle on the through window pair. If I wasn't convinced this was waaaaaay too old, I'd say it was part of a laser range finder. It's nicely machined, if I had to guess, I'd say it's German, and pre 1965, maybe pre WWII - anyone got a clue?

I am wondering if the device you describe could be some sort of optical measuring device, something you focus on a tiny part and then use a scale inside to gauge the dimension of a viewed part. If this is the case, that would be your big gloat.
Why not take the thing around to jewelers or watchmakers in your area and see if thy know what it is?

I think the "micrometer" part is a rangefinder. I had one somewhat similar to that years ago -- may still have it somewhere in my old camera stuff. Argus cameras didn't have rangefinders until the C3, I think, so one would use the accessory rangefinder and then set the focus according to the numbers on the camera lens.
I'd say maybe this was general jewelry making stuff. Simple tools for general work. The drill guide might be that or a wire guide. Might be for sizing sterling or copper wire...
Al pliers - non-sparking - but also won't crush copper - maybe. Not electrical - Jewelry.

The "drill guide" is definately a threading plate, I can see the threads in the holes. The pliers may be jewelry relatedm after examining them with a magnifying glass, they say "B&B St Paul Minn USA" around the pivot, they are also stamped "W.C.Slocomb Peelew Howe. Co." - maybe that is a hint, though a web search for B&B isn't a good way to find out about these pliers, methinks.

I am sure you are right, that it is some form of a range finder, but the "lenses" are too small for it to be a split image type finder - you can't look through them in any practical way, so I am still puzzled as to what it is part of - it is somewhat reminiscent of Argus equipment - in fact, that is a GREAT hint - I found this: http://rick_oleson.tripod.com/index-172.html - if you look at the picture of the Univex Mercury shows an accessory rangefinder that is very similar to this one, but not identical. it is also a lot like this item http://cgi.ebay.com/Vintage-Leitz-Wetzlar-Camera-Rangefinder_W0QQitem... but again, not identical
So, the search is on - what camera does this go with?
> the aluminum pliers are cute - wonder what they are for - anyone have a > clue?
They sort of look like lead heat sinks for when you are soldering in or unsoldering transistor leads, where the device can be damaged by heat conducted up the leads.

It depends on your needs, but I would consider it at least a serious gloat, personally.

It looks sort of like the kind of rangefinder which would be attached to a camera, but not coupled to the lens, so you can measure the distance and then transfer the measurement to the len's focus ring. Sort of like hand-held light meters, before they started buidling them into the cameras.

Nope -- just the normal superimposed image rangefinder from earlier days of photography.

Possibly pre WW-II, as by that time rangefinders were being built into the better cameras.

Are you accustomed to the integrated rangefinders which are part of the viewfinder in a camera? The ones which put the split image as a small part in the middle of the viewfinder? No -- this is not that, but it *is* a stand-alone split-image rangefinder, I believe. One eyepiece (on the same side as the dial), two small objective lenses on the opposite side -- about as far separated as possible given the size of the device? You rotate the dial to eliminate the double-image in the eyepiece -- by superimposing the two copies of the image -- usually one rather bluish and the other rather yellowish to make them easier to spot by eye.
The missing side of that should close it off to eliminate stray illumination spoiling the separation. It *might* have a flash shoe to fit into the top of the camera for convenience, or it might not.
There is something similar to this, made by Kalart, found on many old Speed Graphic (and similar) 4x5 cameras. The difference is that these do not have the dial -- but rather are connected to a lever which measures the position of the lens focusing track on the fold-out bed of the camera. The same camera also has a separate viewfinder bolted to the top of the camera for eye-level work, a set of wire-frame viewfinders (with peephole) for quick framing, and (of course) the ground-glass focusing screen if you have all day to get the shot right.
One of the interesting features added to the Kalart rangefinder for the Speed (and Crown) Graphics was a small light bulb which is powered by a pair of AA batteries to project two images of the filament on the subject -- and the focusing knob moves them apart or together, to allow focusing in dim light, where such a rangefinder is often difficult to use.
Here is a page documenting the Kalart (at least one version):
You can see a lot of details as to how this one works by going to the various sub-pages. It is a lot more complex than what you have, because it can be adjusted to work properly with different lens focal lengths (one at a time -- whichever one you normally keep on the camera.)
Could you post on some web site (perhaps the dropbox <http://www.metalworking.com> some closer images of just the finder as viewed from multiple sides? What is in the eBay auction is not very satisfactory.
Enjoy, DoN.
