I noticed there are many tricks in gun advertisements. For example, "98%" without key word "original", or "original" without key word "matching", or just posting some pictures with minimum text description, "I don't know, you tell me" -
Since it lost the original windowed grip panel, I would think it's a regular 1902 fat barrel with mismatched grip panels.... probably plus some amount due to the s/n.
Is the situation like a "Party Leader" PPK without the eagle grips, except the s/n range being known in this scenario?
