Wow! Nice guns. I'll take a pathetic stab at identification.
#1 Looks like a 3 1/2 inch Model 27 or pre-Model 27, possibly re-nickeled. It has a Tyler-T grip and stag grips, but the stags may be fakes. They do look pretty real in the close ups, though.
#2 - I'm really not up on these. Its a reblued Smith top-break, .38 S&W caliber. I've always called them "Lemon squeezers", I think the real name is something like "New Departure Safety Hammerless". Nice grips. The three notches on the butt are interesting.
#3 - Colt Police Positive Special, caliber .38 Special. Looks all original.
#4 - Colt DA in .41 Long Colt caliber. Also all original, I think.
#5 - Smith and Wesson Model 27-2, 3 1/2 inch barrel. Looks original. This one is much newer than the others. Well used, the name on the sideplate hurts the resale value, but if its somebody close to you its nice to have.
#6 - Harrington and Richardson .22 caliber. Low value gun, but dependable. Model 922.
#7 - Smith and Wesson Model 60, .38 Special. Someone didn't take very good care of it. Should clean up nice. Stainless steel.
#8 - Another oldie of them lemon squeezer family. Its probably a .32.
They look like a cop's guns. Is there a story behind them?
Hope this helps. PM me if you're interested in selling any of them.
