Paintball tank regulator dvs

Description

I pulled both of these regulators apart just to clean them up both came on tap both came on tanks that were out of hydro but of hydro and dead.
I have no reason to believe that either one of these shouldn`t work.
Is the left tank the DXS bonnett  Came off of 4500 PSI tank. The one on the right came off an 80 in³ Nitro duck 3K. If you need these send me a reasonable offer and I'll ship them.
