Right.
During the strike, Colt's polishers were out, and they didn't have enough people to polish everything.
Since revolvers are harder to polish properly, Colt introduced a series of more-or-less unpolished revolvers with a black, parkerized finish.
These guns were:
The Peacekeeper. Actually the Trooper Mark V.
The Commando. This was a Detective Special, NOT to be confused with the WWII Commando, which was a parkerized Official Police.
The Cobra and Agent. For some unknown reason, Colt didn't give a special name to these two aluminum-framed guns in the black finish.
As soon as the strike allowed, Colt discontinued the unpolished models.
Internally, the guns were made to the same standard as the polished guns, and these were good deals if you could stand the rough exterior finish.
