Just checked the site for a BSTS Python I have. Came back with 1995 and model number of I3061 which is a 6" BSTS. And tried my Anaconda (which is not BSTS but is a 5") and it came back as 1996 and a model number of MM3050 which verifies a 5". Hope Colt keeps this up. It could be a huge help to collectors and a detriment to those that tend to stretch the truth a little bit.
Thanks Colt!!!
