The tube has a small leak in it. I will put a new tube in it. I think Tom Jensen done what ever he wanted to do. I have about give up on trying to figure out what or how he done things. Glad you like the collection I've put together. I've got a crazy idea I want to do (if possible). I want to try and collect all the different versions of the model 10s. Dont know if I can get it done but I'm sure gonna try. So far I have 8 different ones now and still hunting.
