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.

Like that box!

"The stamp is on the sidearms, not on the back of the frontplate".

What is the stamp? photo?

The content 'stamp' doesn't look so good,,but,,,IF that really is a separate front plate,well,that's hard to fake. The flag colors should be real glassy enamel.
*The variant has a edge decoration,,IF that was trimmed off you would have the front of this ring exactly.
So far its got more good on it than bad..
