Hi Daryl,
I may have a spare mp15dc to sell but there are some issues. First, everything is in storage at the moment, although I expect that to change soon. Secondly, I'm not even quite sure whether I have a new gold version in my pile. I've bought a bunch of the switchers as kitbash fodder, and haven't always been concerned with 2-rail versus 3-rail or powered versus unpowered. Also, you say paint scheme doesn't matter, but what about shell style? There are three hood configurations. Do you care which style hood is on the unit?
If you have a month to wait til I have things out of storage, I'll be happy to check my stash.
Jim
