Yup, it's what been dubbed an Acusport Bisley. Acusport, like other distrbutors, will contract a manufacturer to produce non-cataloged variations exclusively for their own distribution. Acusport started this stainless Bisley series years back and now have 5 different models in it. I believe in the two runs of the 45 Colt model, there were 1200 produced. They won't command the prices the models in .44 and .41 magnum will, but hold their value very well. I have 7 of these gems and I can say the 45 Colt one, the only shooter of the bunch, is my favorite revolver. Handles excellant! If you got one locally for a good price, buy it!
