I appreciate that Texas Star. It has an exposed ejector rod and it is almost the length of the short barrel. So that seems to correspond to the 1961 date.

My photo box isn't set up so I can't post pics yet.

Thanks. Take off the grips and see if the frame is full length. I just recalled that about 1966, the steel frame was shortened to the length on the Agent .38 for all Colt snubs and PPS guns. On these later ones, the wooden stocks come down beyond the shorter steel or light alloy frame on all but the Agent model.
