TexasJim50 Our local pirate gas outfit makes their own slick neck bottles,chuck em up turn em smooth then rough stamp their name on it. I was at their facility it was packed with bottles,Kenny said this isn't 1% of our bottles !! Bought a lease from them for 55$ nearly 60 yrs. ago hasn't cost even a dollar since. Used to be very reasonable but Kenny and his brother passed and the daughter got kinda greedy but has since kinda moderated. Lost my contract (paper) but got a letter from them (they thought maybe I'd croaked I think) which proved my contract...so keep on keepin on. Both gasses plus nitrogen in a not even contracted bottle I traded for oh 20 years ago. Torches,mig,stick all family tools some about 80 yrs. old.
