Freelancer with a full gig schedule here, I found out this morning that I require pretty serious shoulder surgery that will put my support arm in a sling for 6 weeks. Last fall I saw the Seatbelts, the bandleader was a bone player with an arm in a sling, and he had a trombone stand rigged up such that he was able to play intense licks with the slide arm only. I'm not talking about ergobone or spinesaver, they sound great, but they require a support arm.

Can anyone here identify the product? Or offer a used one for sale? I imagine most guys who use this do so temporarily.
