Hello from Waterloo… No – not that Waterloo…

Greetings from Illinois and near Waterloo (IL, USA)

If you can find my photo album on this site [ not sure if I can link it directly here since this is my first post ] you will find 3 photos.

#1 is the photo of the device as I found it in a box with Fleischmann N scale traffic signals. It is a plastic box with a wood insert & the insert appears to be glued in.

The two holes at the top are drilled at an angle [like pocket screw holes]

The bottom holes are labeled with stamped ink [as opposed to transfers or decals]

#2 is showing the "clamps" removed from their pocket holes. It appears that these were intended to be used as some sort of holding feature, although you would not be able to have any sort of serious tension due to the flexible nature of the thing.

#3 is a close up of the "clamp". The upper part is concave about the radius of a ball point pen insert. I believe the normal position of this closed with the bottom arm going up into the concave area and then you tighten down the knob.

In the wood fixture it appears that this was used with the "clamp" wide open and used backwards [the finger being bent backwards so the tip is the mating surface, vs. the sprung contact.

I have attempted numerous google image searches, and most of the model train tools/jigs over here to no avail.

I have pondered catenary jig, pantograph jig, but I can't see that being of much use due to the lip of the case.

I also can not attest that this has anything to do with model railroading.

The small holes are smaller than the normal rotary tool [dremel] bit size.

There are no indentations in the foam to suggest anything was stored in those holes. And you can see the foam shows where the "clamps" hit.

I also did some searching for sewing machine items, and this could not be used on a machine [too thin] and it did not appear to be anything of use in bobbin setting, etc.

Thanks for looking!

Trying to figure out that this thing is….

Welcome to the Forum!

From the holes, a box intended for storing things with a standard mounting pin.

Sewing machine bobbins usually locate on a pin, rather than a bore.

Whatever they are, the centre distance suggests that they are fairly small, mand the size of the box suggests that the lengths do not vary a lot.

The two,, for want of a better word, "clamps" appear to be handed, so that one might be Internal, and the other external.

Sorry to have contributed so very little.
