WHAT DO YOU WANT TO KNOW? PROOF/CONTROL MARKS

[kahnjar1]

Hi Bill,
Marks are Belgian Proofs as follows:
The oval ELG in use from 1810 and was the SOLE MARK until 1853.
The EL intertwined was introduced 1852.
The numbers, 18 and 17.2 are the bore size in millimeters. Introduced 1810 and until 1894 graduated in 0.2mm graduations. After that date in 0.1mm graduations.
So from the above, your pistol is likely post 1853 and probably pre 1895.
Not quite what the guy in the shop said, but the marks tell the story.
Nice piece by the way!
Regards Stuart
