Was that ever common.?
I am 65 and do not remember seeing that from Kodak or GAF in the usa.
I suppose i might not have realized that they were reloadable, perhaps.?
Ansco was always reloadedable. Kodak started the crimped ends in the mid 1960s in North America, but I did get a few non crimped "grey Market" ones from Kodak Limited in teh early 1970s.
one of the go arounds for starting photographers was that Ansco sold an "easy Loader" with 8 lenths of 20 exp anscochrome, and they sold a package ot 8 empty cassettes to go with it. (when I was selling cameras one poor lad had used one to load some tri-x but just labeled it with DYMO tape. the lab of course ran it through the Anscochrome line with predictable (blank) results.)
Ilford at one time used aluminum cassettes - but in the 1960s switched to the same cassettes used by AGFA, which were simalar to the ones sold by AP for reloading. the older ones have the film slot coming out radially to the cassette, so are not good after the cameras started having a window to show the film type.
Fuji and Konica were also reloadable beofre the advent of DX.
once DX came out almost every brand came out as crimped.
