Ok, I took it Baum's music our local repair shop, Kayte did a great job on the basics of getting the horn playing well. She found 3 leaks in the horn, mostly someone tried to repair it without cleaning up the old solder, just sort of tried to glop enough solder on it to make it work, well it didn't.
WE got the 3 leaks fixed got the horn a chem clean, she told me that as she started dipping the horn in the chemical bath a spider crawled out the bell, poor guy, had a nice place to stay till then, well that's life. Lots of dirt in the valve section, still NOT happy with the valves, they need to be worked over, they are not smooth, lots of effort required to make them work. I'm sure they have plenty of rust issues in there. We were both surprised that a horn from 1970 B-337, did have any red rot but it was clean. The bell looks horrible, someone tried to roll out the dents and left all the crinkles in the bell, people keep asking me if it's my marching horn. BUT, I don't mind older horns, so it doesn't bother me to play it, needs to be buffed out all over the horn, most of the big dents are gone, it's a work in progress but progressing nicely.
Hope all of you are doing well and having fun out there. I did premier a new tuba solo on it a week ago with a local band, horn did fine. If ANYONE knows of or has an old Model 20 bottom rotary valve cap cover they would like to sell, let me know. The NEW model 25's are too big, I have one, doesn't fit. It's a smaller cap. Perhaps someone has one in a junk box somewhere????
Thanks for your help.
