Anyone know what this is?

This strange instrument was found amongst the workshop I purchased from a retired engineer/modelmaker some years ago and it has confounded far more experienced brains than mine. I also acquired at the same time a large collection of ME mags going back to the 1950s and searching them has not yielded anything.

It fits the lathe bed of my Myford 7 and has a toggled centre pin enabling  maybe a disc shaped workpiece to be mounted under the swivelling pointer arm.

 

There aren't any graduation markings visible.

 

Someone out there must have an idea!

Is it for use with an indexing wheel?

That has been suggested before but the indexing wheel that I acquired at the same time had no chance of fitting and even if it had I can't see how it would work.

Try asking on Homeworkshop.  If those guys don't know, then nobody does

Looks a little like it may have been made for a specific job, perhaps to align a part when setting up ?.  It's not unusual to make a fixture to help speed up a process.

A tad late, so apologies. Is it a base for a DTI clock?

 

Cheers,

Edit. Having had another look, it appears to be an adjustable angle bracket to hold a clock via and onto the lathe bed. The profile of the lower segment would appear to be a centre-specific piece. The upper portion likewise.
