Wonderful Antique Violin Makers Plane

I bought this wonderful little plane from a local antique dealer. When I say little, I mean little, it's just over 1 1/2" long!
I've never seen a dovetailed violin makers plane before and it looks great with the contrasting metals. I've looked back through my David Stanley catalogues and can see nothing like it. The condition is very good and the workmanship on this tiny scale is superb.

The mouth is skewed and very tight, this plane was obviously made to be used as well as admired.
If anyone knows of another one like it, I would like to hear from them.
