So was there really a problem sourcing these from outside the company, or is it just being a cost advantage and maybe to ensure supply? Other film makers don't seem to have a problem getting cassettes.
I know Freestyle dont sell the metal snap cap cassettes they used to, due to them not being available from the manufacturer anymore. They only sell the plastic ones. Im under the impression that Efke, Foma, Adox, Rollei, etc. all sourced their cassettes from this same manufacturer - maybe Ilford did as well. I would expect Kodak and Fuji make theirs in house as well, but HARMAN might be looking to offset their investment by working with the smaller manufacturers to provide cassettes to them too.
