My MV50 is up for grabs. It has been somewhat modified:

Perhaps 5 years of use. Zippers on the case are good. One of the snaps is broken (visible in the pic). The case is wearing thin in spots around the compressor.
Perhaps tonight, when temps cool, I'll perform an air up timing test (35" x 12.5 x 15's from 12 to 24psi). 12psi to 24psi took 6 minutes (clocked).
