For the Trans Am in 1972, the SCCA issued Brass Tags and Log Books to the various cars running that series. The tags were usually riveted to the cage. Both Brass Tag and Log Book carried the same number in the following format. For large bore A-Sedan cars: "72ASxx", where xx is a number. For the 2.5 challenge B-Sedan cars: "72BSxx" . The one log book I have seen had this number on the cover, the serial number and other technical info listed in side and was issued and dated by John Timanus and there was a charge of $100. That particular book was issued later in the season at Laguna Seca and was issued on the Friday before the race day to a car that was making its 1972 debut at that event. The number was relatively high.
My questions are, is there a list from SCCA showing which Brass Tags/Log Book were issued to which chassis? I would also like to know with certainty if the Brass Tags/Log Books were issued only upon inspection on the race weekend, starting at the Lime Rock event in 1972. Or were there other possible issue methods. Also If anyone knows with certainty that the Brass Tags/Log Book were issued in sequential order, so "72AS01" and "72BS01" and other low numbers issued at Lime Rock.
By way of introduction, as this is my first post to this great forum, I am Ken Geiger from Toronto and I own an Alfa Romeo GTA that ran the Trans Am in 1966, 1969, 1970, 1971 and 1972 doing about 30 races. She carries Brass Tag "72BS06" and she ran at Lime Rock in 1972. I have collected a few tag numbers for the B-sedans and seen a couple on the Big cars.
Thanks and Regards
