Hello, I am selling a set of Acetylene UN1001, 36 3/4" Tall and Oxygen UN1072, 56" Tall, tanks. I only have the tanks no regulator, hoses or torch. I am not sure if these contain any gases in them. I got these in a storage unit, don't know much about them. I am asking for 450.00 or best offer. Thanks for looking, if you have any questions, comments or concerns, please contact me anytime. Enjoy the rest of your day! Take a peek at the other items I have for sale.
