From what I can tell it was last available to purchase around 1965 from the CIL catalogue. It was a low-end .22 rifle, but it shoots damn good.
They sold it for $18 in 1965 so in 2012 dollars which would peg it at around $130 today, which seems about right. Its a great gun, but you can tell its low-end.
I'll try to post better pictures later on.
