I found a nice specimen this week. It is a J C Higgins Model 41, a single shot .22 (S, L, LR) bolt action with a full size wooden stock and barrel. It's in very good shape for a pre-1968 rifle (it has no serial number). No rust, no rattles, no cracks in the stock. Plenty of character in the old wood, though. The rifle was used a lot but never abused.
In doing the research on it, these were made by Marlin and sold by Sears Roebuck. It is a slightly cheaper version of the Marlin 101 Crown Prince, which was offered only 1 year by Marlin, 1959. Here is a pic of the Marlin:
The "lesser" versions were sold by various department and auto stores in the 1960s. It looks like the main differences are, the Higgins has a plastic trigger guard, the Marlin's is metal. The Marlin has a white stripe between the stock and the butt plate, the Higgins does not.
The hammer has to be pulled back manually against a spring tension. If the hammer slips as you pull it back, the rifle will fire. Some versions of this rifle have a ring on the hammer instead of the knob pictured above. Your finger fits in the hammer ring and won't slip out, making for a more secure cocking procedure.
I believe the barrel has the Marlin micro-groove rifling, but I'm not sure what to look for. The sights are sturdy and usable. I found it in a LGS, marked down from $129 to $101. I still need to take pictures and do some accuracy testing. So far I've just function tested it.
I think I'm going to really enjoy this rifle. I'm used to single shot pellet guns, so the loading procedure doesn't bother me at all. Each shot is special this way.
