On reflection, I realized I left out a couple of Colt DA target revolvers whose condition or interest meant they could have been included in my earlier post in this thread. So here they are now. Again, they are older specimens.
This one is an Officers Model in 38 Special from 1920, serial number 451417. I can shoot this one a little more accurately than my K-38s, perhaps because it is slightly heavier and I do better with heavier revolvers.
And then there is this somewhat rare .32 Officers Model from 1940 or 1941, serial number 643916. I think this one is unfired.
