I saw a post on here a while back about a visible pump that the skins looked like they were slightly bent about every 1/2" all the way around. I do not have pics but I figured someone might rememeber what the pump was and tell me. My sometimers disease is getting worse. Thanks for the help.

I think most thought it was a Clearvision. But I don't think it was confirmed.

Looks like a clear vision to me. JMO
I had just bought one of these a few weeks back also. Mine has the tag from Clear Vision still attached to the skins(also break-bent). It is somewhat damaged, but I'm confident it says it is a Model G9 517 . The cylinder is etched on two sides with the gallon markings.
