So, an old relic was shot to pieces, neglected until pitted, rubba-dubbed to make it sparkle,then reamed out to extract some salvage value from it, and it's still someone's "dream gun"?
I'd say that it was definitely not their (the seller's) dream gun. At least not anymore it wasn't.

The "name", model, or description might be a dream gun, but not this actual gun itself.

"Buy the gun, not the name."

Out there doing it best I can.
