I have three early bend stainless steel (non-magnetic) gas tubes. Tubes only, no pins. These are used tubes. The nub is worn smooth on the end. If interested, please email me at email@example.com instead of posting an "I'll take it." I have limited access to this site during the day. $50 shipped each. Money order or Paypal.
All three are SPF.
Posting for feedback. Item received, thanks.
