but maybe I missed it. Anyway, I can contribute the fact that I have a 25-11...these were all in the Lew Horton Heritage Series. There were about 150 made with a blue barrel and color case frame in 45 Colt. The serial prefix is GBP for these. But they also made about 150 in all blue with a serial prefix of BAK. Look at page 348 of the standard catalog, 3rd Ed., for information on these two varieties of 25-11. I have an all blue variety in the BAK serial and my serial is lower than the BAK0016 that is the example in Supica/Nahas. They have a 6 1/2" barrel with Patridge gold-bead front sight. Gorgeous gun and I bought it three months ago for a shooter. It is wonderful, wonderful shooter. This is one I will have when I pass on one of these years. Oh, maybe it is obvious, but if not, this is a Performance Center product and shipped in 2001.
