HO Scale Athearn Southern Pacific Cabooses 2 Of Them

HO is actually a gauge which refers to the width of the track. 1:87th is the scale but HO Scale seems to be the term everyone is using so I will go with that.
I saw this attractive pair of HO Southern Pacific Cabooses at the same mall as the Kingfisher model. There were a few other contenders but I decided to go with these. As I suspected these are Athearn model railroad kits. Athearn made easy to assemble well detailed models. Although I have a pair of their locomotives which are not easy to assemble. I suspect materials shrink and expand of the years. Anyway I can usually get the cars togethers pretty quick. I used to buy these in the 70s and everything fit together quite well. A kit from the same time now not so much. These cabooses have the old style couplers so these are from the 1960s-1970s. The models are of steel body cabooses so I am thinking 1930s-1970s. Wood body cabooses tended to splinter when derailed.
Caboose is photos 1&2 are of a copula caboose. This is the most common type of caboose with variations.
Photos 3 and 4 are of a bay window caboose. The bay window caboose featured a breakfast nook (not really). It gave a better view of the side of the train and had super cool swivel chairs. I had the chance to buy one once and passed it up. My bad.
Eventually these were combined with the extended vision caboose of which I currently do not have an example. But then again maybe I do, I will have to check.
