Am I seeing right? A "no safety" Pigeon Gun? Your title said C-Grade. The pictures showed ejectors. Charles Semmer did an article on CEO-Grade 132037 in The Double Gun Journal, Volume Five, Issue 2, and on page 140 there is a picture of the barrel flats and bottom of the barrel tubes with the same ///O. The O I'm thinking means "Ordnance" as there are Os on the bottom of the tubes of my DEO-Grade in the 132000 range. Also, on 132037 there is a C to the left of the serial number on the barrel flat, and it has the 2 3/4 markings just forward of the barrel flats. Charles also covered 132037 on pages 222 and 223 of his book. I spotted something in his pictures today that he doesn't mention in either DGJ or his book, a May 1923 Remington repair code (KP3) on the web between the barrels.
My CEO 12-gauge, 135944, has no C on the barrel flats and is marked ///M on the bottoms of the tubes?!?
