I bought this MK7 for the second stage attached to it. I don't anticipate using this in the future and I do not know its service history, it seems to work when I tested the reg on a tank. If anyone is interested please PM or email me. I have it priced at $35 obo + shipping (around $10 USPS). Paypal would be ok. I have a couple of pictures that I can send.
Thanks
Doug
