1964 Det Spl 2" with shrouded barrel

Looking for some info on the above described handgun. Verified DOM was 1964, it has a long frame,round butt and a shrouded barrel. I have been unable to get a definite answer from Colt if this was a factory made gun or somebody's gun smithing work. Gun is in excellent shape and I have not seen another one like it. There are a bunch of them with the exposed ejector rods but none I have been able to find like this one...All info appreciated.

sounds like a series 3 barrel on your gun, if the gun was infact made in 1964, they had a post 1973 shrouded barrel added to it.

If it was an add on, it was professionally done. The wear on the metal is consistent throughout the gun.

if the original was a safe queen, the new barrel would be a good match 9+ years later when it was altered OR it was refinished when it was re-barreled

Definitely not a reblue.
