I found a CST on an internet ad a couple weeks ago. I spent the rest of the afternoon reading many articles on them. But, this one was the most interesting, and I used this thread as a guide, to buy it. The seller thought it was a Model 50 and there were 1100 made. After buying, I told him what I found out in this thread. So, I would like to thank the experts on this forum for educating me on the CST!
It is serial number 57740 and I believe it to be one of the first 114 made in 1955. Please correct me if I am wrong. The condition is very nice for it's age, but not perfect. The numbers on the frame, grips, barrel, and cylinder all match. I will post pics in a few days for viewing.
Thanks for the education!
