No idea what kind it is. Has a green hose.. hooked it to my "E" cylinder and O2 shot out the base and sides. It didn't go up & down, maybe I did something wrong. I bought it for .50 cents at a flea market. The people selling the stuff had no clue, and didn't know what it was for. Also got a huge trauma bag packed full of dressings for 10 bucks. These people were a few short of a six pack. I could have sold the bag myself on eBay for over 200.Originally posted by TTLWHKR+Mar 29 2005, 10:16 AM--></div><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td>QUOTE (TTLWHKR @ Mar 29 2005, 10:16 AM)</td></tr><tr><td id='QUOTE'>
I want...I want...
When I get a good deal, I always say "Boy this would have cost me hundreds anywhere else". Just to make them feel ripped off. [/b][/quote]
No - the Thumper folks are on their 4th or 5th gereration machine - that's why I asked.
