Hey Guest!
Likely - here's one currently on eBay - TS78909L. Still, best bet for actual build date is the BMIHT certificate. Also gives details on equipment, color and trim supplied.My guess is a 1961. They only made like 400 or so in 1961 and the rest after that were tr3Bs, so the last run should be clear by subtracting the last vin made from yours.
