Ek

It is a Wiedmann. You can tell by the disc (only maker with a rim) and the pin setting low on the cross. Jim

What the heck happened to the back, are they all that way or do you think it was sand blasted at one time ?

Thanks Jim ..........

There is one in Gordon's book page 128 looks like the same maker and the back is sand blasted the same way.
