The dive club I belong to has been gifted a large quantity of vintage gear. This gift was made by the widow of John Baldi. John was a scuba pioneer in the early days of diving. John owned and operated South Shore skin divers in Quincy and later Weymouth Ma. There are double hose regs made by US Divers, Nemrod, Healthways, Dacor, and New England Divers. I've seen single hose regs from New England Divers, US Divers, Dacor, and Healthways. There's a Scott Hydropak in the mix and a set of USD triple tanks. There is WAY too much to list everything. If you're looking for anything in particular shoot me a PM, I'll look to see if it's there. I am VP of the dive club so I have a fiduciary responsibility to the club. That means you're not going to get the USD triples for $20. All this equipment is located in Lawrence Ma., if it needs to be shipped it's on your dime. Payment is Paypal friends and family or cash if you're close and want to pick it up
