69 COPO M22 Transmission?

[Richard Shrivel]

I am pretty new to this site, but I figured someone would have an answer. A friend of mine has a M22 transmission that still has the little metal tag on the sidecover bolt, that according to his research and from a National Chevelle Newsletter indicates that it is a 1969 COPO M22, not sure if its for a camaro or chevelle or if there is a difference. I personally haven't seen the numbers on the tag, but I have seen the transmission. There is no VIN number on this transmission. Does this sound possible? I was cosidering purchasing this transmission, although I don't have a COPO to put it in. Any idea as to what it would be worth if it were to be a real COPO M22.
