that's about right..if you can even get it serviced you are looking at about $140 to do so plus what ever you pay for it.I haven't seen one of those since the mid/late 80's...I believe that was the only model ever made with that bell shaped 1st stage. IIRC the 4th port was for a drysuit inflator.
assuming it's all the same vintage - $25? Hard to tell from the picture but the console looks like it could be a newer Sherwood - if so - $50?
