I recently by chance found the FN 49 Sniper OIP Scope in an antique shop and have tried to determine which variant it is. All the other threads refer to Luxembourg, Belgian, Egyptian and other. The numbering on the scopes clearly shows where it is from, but my scope does not have any of these codes. Mine shows markings of C.B. F.P. No 161. I can not find any reference to these codes on the internet. Has anyone seen this before.
