got a chance to shoot this today. serial number on the frame shows it is from 1913, it is 259XX. the slide has a small gouge in it, right where the pony is (in the center of the slide, not at the rear), only major ding on the whole gun. on the top rear of the slide just in front of the rear sight is a P and on the barrel there is a 5. no markings on the right side of the slide. the small mark above the mag release looks like a M or W inside a C or O. flat, smooth mainspring housing with lanyard loop. grips are mismatched; the left has the colt logo, right is newer plastic. magazine is not original. any info is appreciated, thanks!
