Hi everyone!

I have contacted a manufacturer in Texas who is willing to make J3 expander tubes! I will have to provide the specs and give him my old tube to reverse engineer. This is a large aerospace manufacturer who will have to get orders for at least 100 tubes before they can commit to manufacture.

I'll take 2 or 3 and would like to know if anyone else would be interested in buying some? I don't want to do a conversion and want to keep my old hydraulic brakes.

Please let me know if you want an expander tube and how to contact you. I hope this is possible because I just joined today. Thanks!

P.S. If anyone out there has a drawing of the expander tube (with measurements) please provide a copy. I have the original patent, #2,256,431 from 1941 but it does not have the specs, only concept.
