This six-window design was the first caboose manufactured by Bachmann (dating back to the late 1960s), and as of this 2012 writing, Bachmann is still cranking them out (albeit only as part of a trainset). Both Atlas and Life-Like have offered similar six-window cabooses (the former manufactured in Austria and the latter manufactured in Yugoslavia). The same Bachmann model was also sold in "Parkway Industries" packaging (some sort of Bachmann subsidiary). Same box, same model, different brand name.
These models have metal wheels and shell-mounted Rapido couplers. They are stamped "Bachmann - Made in China" on the bottom.
I'm told that this model is based on a Grand Trunk Western / CN (Newfoundland Railways) prototype, shortened to fit the 30' underframe.
These same models were also distributed by Tomy in the 1970s (probably only in Japan). Same packaging, but with the Tomy name added. EG -
They were also distributed by an obscure outfit called "Bronco Electric Trains". Once again, same packaging -
