Your 185 Quality Lindner Daly was made in the 1907-08 time frame. The action, forearm iron and trigger guard were case hardened using the bone/charcoal method. The top lever was nitre blue. The barrel rib should say"Krupp fluid steel". All Damascus barreled Lindner's said "Fine Damascus" on the rib. I think Daly quit offering Damascus in 1901 or 1902. I hope that helps. These are truly wonderful guns. Good luck!
Cheers,
