Identifying An Old Key

I acquired this morse key about 25 years ago. A few years ago Bob VE3DUB (SK) made a nice oak base for it and put a knob on it. At that time he told me it was a very rare key. There are two marks on it – the initials GNW and 1795 – as seen below.

Not sure if any of my readers can identify it. I’ve spent a good deal of time on Google trying to datamine information about it.
