I have a couple of Detective Specials, a shrouded version, and an earlier version without the shroud. Here is the Shrouded version, can’t find the serial number in the Colt database, so not sure when it was made:
Here is the pre shrouded version, with the Tyler T Grip. In this configuration it fits in my pocket holster, but with the larger grips from the model above, not so well suited for a pocket gun:
