Watch auctions and classifieds.
Even the rarest of parts come up every now and then.
But how long are you willing to wait, before something pops up? ... And then gets caught in a bidding war between two idiots, and the winning bid is greater than the average auction price for a well-worn but complete and functional 9422. ...And you have to start all over again.
I'm with Scorch. Auction that lot off as a "parts kit", to someone with aspirations of grandeur (or a 9422 receiver on the shelf). Or go piecemeal and mete them out over a couple years.
Personally, I'd rather dump them all at once. I've done the piecemeal approach with a couple parts guns or 'parts kits' that I sold, and the prolonged hassle wasn't worth the small extra profit. In one case, I never did sell about 80% of what was listed - even though the parts seemed to be in high demand by owners. (The remainder of that one is all in a zip top bag, gathering dust, now...)
