I think when T/C had their big fire in what? 1998, it was the beginning of the end for them. I think that was about the time when the bean counters took charge and decided that it was not a good business decision to keep the low selling items in the lineup. So, goodbye to the .36 and the .45 caliber firearms. And of course, with those gone, there would be no need to keep the accessories for those calibers in stock, either. I might be wrong about the above, but that is how I believe the T/C rep explained it to me. Please correct me if that is wrong.
So, jags, ball pullers and various other accessories. T/C did not make any of that, they sub-contracted with other companies to produce them. That could explain why the design varied over time. Company A makes the jags for a while, then Company B comes in with a better price with a different design. Presto, all of a sudden the design changes and another company is making them for T/C. It's all about nickels and dimes.
