~~~ private club in Madrid, Spain.

Doe anyone have any additional information?

I had the 100 seen below... and just added the 1000 and, now searching for a 500 which would probably be an oval or possibly 44 mm octagon.

I'll submit better photos of the plaque to ChipGuide, tomorrow.

Also, this is the first time I have seen this type of engraving in the shadow of the fold and creases on the fold; seems very unusual, l to me, anyway.
