First New Years Mystery Item!

[Martin King 2Participant @martinking2]

Hi All,

Sorry to have been so tardy but have been very busy with lots of tool restorations and listings. All tucked in with some very nasty bouts of BPPV, less than ideal!

Michael G: I have checked the markings with a good vcaliper and they are all spot on inches and fractions, all the same width so no vernier.

F Fury: I have had several coopers croze tools and all have bee pretty much on the rough and ready side rather than precision as this part indicates. I do however feel you may well be on the correct track..

What may not show clearly in my photos is the fact that the grooves are cut very much at an angle to the plane of the main surface as if they were to take a sliding part of some sort. I agree that I have the photo upside down almost certainly.

Curiouser and curiouser! Cheers, Martin.

Engraving-machine copy-holder? I don't think it was that.

The ratchet-like angles of the steps are quite clear, and I drew attention to them a while back as perhaps a way to step something over another part without raising the overall height too much.

The wood-working theme seems feasible, and I'd suggest there it might have been part of a setting-tool for some sort of special-purpose plane, morticing-machine head or similar; possibly specific to a particular line of wood-work.
