I have a similiar Daily with Lindner stamping on the barrels. S/N 3262. The APN is 1220. Top rib engraved Charles Daily Extra Fine Damascus Diamond Quality. Dolls head rib extension and cocking indicators. No proof marks, no country of origin. Looks like Herringbone Damsacus barrels. All screws still timed. Blued frame. Straight back frame.
When I bought this gun, I cooresponded with the late John Mann, who figured the manufacturing date as between 1880-1890 due to lack of proof marks. Further coorespondance with Ken Georgi comfirmed the estimated date.
This is an extremely beautiful but heavy 12ga built with a short stock leading me to assume it was a water fowling gun.
Hope something here will help the OP and those who have thus far responded.
PS: I thought Lindner used Saur frames and that even GEORGE Lindner used a barrel stamp to identify. I'll dig back int John Mann's DGJ articles when I can- busy right now.
