Looking for info and value on this gun. Haven't seen it in person yet, but this is what the seller tells me:

Imported S.A.E. Miami FL, says Grulla on the water table, serial 302XX, 90% bluing, 97% overall.

Can anyone tell me when it was manufactured?

Anything about "S.A.E"? (Could that be U.A.E.? maybe he is losing his eyesight)

Approximate value?

How do these compare with modern Grullas?

Thanks.
