They are rarer than a hen's tooth these days. They do pop up on eBay periodically but I have not seen them sold "new" in a US tack store in a long time. They are a very standard reddish color that oils about to where Edgewood colors to. So you should be able to find a match with another company if you need to.
You could check with Horseloverz they were the dealer for Jaguar in the past. I was at there store in December and they had new saddles marked Jaguar/(something with a C), could have been Crosby or Collegiate. I did not look at the bridles.
I am a licensed Jaguar dealer. I don't want to break any rules on this board but my company's name is Chagrin Saddlery. I will have no problems getting them for you should you want to order. Thanks. Dana
