The A.H. Fox Collectors Association, Inc. has photocopies of the graded gun production cards, including the SBTs.

Dues paying members of the AHFCA get one free look up per year, and additional look ups are $25. Members make their request on the "Memebers Only" forum on the web site, one of the board members makes a jpeg of the card and emails it to the member. A lot faster then getting a letter from Savage once your membership is processed.
