As a group we started trying to put together a list just to give an idea on production dates some months ago here. It didn't get very far, but I saved what little was offered. So I'll just toss some of it out there for speculation. Dates/numbers are as per offered by members so take them for just that...
TC told one member that they had different serial number ranges for each model.
TC was started in 1967 to produce the Contender pistol, but it was thought that the earliest Hawkens and Renegades didn't come along until in the 70's (when I bought my first 2 Hawkens).
Even so, a member gave a Hawken kit as 1967 in the 24XX range (although it should have a "K" prefix if an early kit).
Renegade numbers/dates that were offered:
Bought new -
1971 15807
1979 26XXX
1992 319XXX
1993 353XXX
My Renegade 54 is 4-digit at 65XX. While I bought it LNIB from a collector, I didn't find it until 2004 and have no information on when made.
Your serial number 65510 doesn't fit in here anywhere for an early Renegade - sounds more like a very late production or just before they were discontinued??? :hmm:
FWIW,
