This is for sale on a dealers site. I know this pattern, but there are differences. Normally the sides on the frontplate are ornamented. The stamp is on the sidearms, not on the back of the frontplate. Also the stamps looks a little bit crude.
Before i buy it, i hope you can help me, finding if it is either a variation of this pattern or a good fake.
