Winter Hawk -
You could very easily be spot on about the Renegade. As I said, it first appeared in Gun Digest in 1976, which is not considered a reliable source for the start of manufacture but sure could also be spot on.
Tying memories to specific things in life can certainly help folks date those memories. But others have "remembered" the Renegade from as early as 1971 and there is currently no way to prove them wrong.
Even so, your input adds one more to the list who remembers around 1976, and someday maybe that list will have enough entries where a majority in agreement on the first year can generally be accepted as the best speculation of the first year. If it is 1976, then my Renegade is probably 1976 but could be 1977. Also speculation as we do not know how many per year where made or what the starting serial number was.
Only model that is pretty much certain is the Hawken being first offered in Aug 1970, IF you believe that when TC released and celebrated its 25 year anniversary model of it in Aug 1995 it was exactly 25 years later.
Thanks for your input pard, and for scratching that itch...
BTW, I guess I am the only clown out there who has kept receipts/complete records of all his firearms bought and sold over the years since I was old enough to think it important. Doesn't help with my Renegade though as I bought it used 1/2004.
