James, some pictures would help but it seems like you have the standard markings for an Erfurt. The right side should have 3 initials that look like crown B C S and then the eagle most forward, these are acceptance stamps, not proofs. The 8.82 is the barrel land diameter in millimeters. The trigger guard stamping is similar to the others.
Look for proofs on the grip screws too, also on the forward part of the 'flat' just above the right grip and there should be two proofs on the barrel, one on the left and one on the right top.
