I'll give your question a spin from memory, but I'd have to go dig my files out of storage to be sure I didn't miss any.
The Super 16 came out in the very late 80's for the handguns and to coinside with the new youth model carbines. They were offered for at least the 22LR, 22MAG, 223 Remy, 7X30 Waters, 30-30 Win, 35 Remy, 44 MAG and 45/70. About a year later a 16 1/4" vent rib 45/.410 was added, and 3-4 years after that the 22 Hornet Super 16 came along. I don't remember if others were added later, but I don't believe any of the standard production Super 16's were 45 Colt only. They could have been special ordered from Fox Ridge though.
HTH,
