Tig welder for a beginner

I’ve had an OLD 300A P&H lurking in my garage for some years now. I took it in on trade for some tools when I was a Snap-On dealer (circa 1978-85). It is AC only (although I’ve been told you can buy an inverter for it), has a foot pedal that looks like it came out of an early gasser, and a water-cooled tig torch. I loaned it to a buddy who was an old Ironworker and welder, and he kept it for about 15 years. It needs to be fed with a 75-100A circuit to use its’ full potential. I only used it a few times, and have very little tig experience. Is there a market for something like this? I’ve thought about listing it, but it is really heavy and about the size of a refrigerator. Not really easy to ship. It would be great for patching up the Queen Mary or a tank.
