I have 3 of these that I used for my rebreather. I upgraded my rebreather mounting system and now these are not usable to me any more. They are in perfect working order, just some discoloration to them. Located in Raleigh, NC. $20 each. Add about $6 for shipping to lower 48. Paypal is OK. If you are also interested in 1 inch cam straps for the pony bottle I have those too. $10 each. For quickest replies, email me at nccavediver@gmail.com
