Unknown Supex Cartridge

I just came upon an unknown Supex Cartridge. The body is gold metallic, but it is not the 909 cartridge. It has a black facing and nothing identifying its model number. The only thing it has on it is "Supex" on the front panel. I would like to talk to someone who worked with Supex's back in the day. I will provide pictures by email.
