Maybe and odd design of tap wrench where one of the handles that should be on the top bar is missing. Or on some the other one would be on the lower half.

Probably not – but it can be surprising what people do at times when making things like that.

Yes, lathe carrier I expect.

I have one too Alan. Came with a hobbymat and like this one if it is the square part of the bars is too long really,

But only one handle? I can't see anyone using it as a carrier. Why the small V's?

Maybe it's multi purpose. The screws are suitable length for a toolmakers clamp.

The best "home made" one I have seen was my Dad's but it will have been made at work to use.

A square, slightly oblong made up of 2 parts with the usual V in them where they join. Opened / closes just like a toolmaker's clamp. The threads having long handles rather than the usual clamp type shown in the shot. The handles were tapered too widening towards the parts that grip. Compact and able to hold a pretty large tap or reamer. I'd say it would probably hold a 3/16" tap and upwards very firmly. Sort of sizes a toolmaker would be interested in.

The handles were maybe 1 1/2" out of line so it could adjusted just like a toolmaker's clamp is.

Looks like I have misplaced a screw.

We used something similar when I was a lad as straps to hold small items while being drilled, much easier than mounting components in a drilling vice as the components are lying flat on the drill table. Toolmaker's clamps do the same job as well.
