Vintage parts values are an odd thing to pin down. When you have it, and don't need it, it's worthless junk. When you need it, and you can't find a replacement anywhere, it's priceless. Somewhere in the middle hopefully you'll be able to find a happy place for both of you. I think Ewe's offer is more than fair especially as there are probably only a couple of folks in the whole country who need specifically what you have at any given time.
I gutted a '63 Flying Cloud some time ago and had some really nice parts that only took me two years to find a home for. But, I couldn't bring myself to chuck 'em as I knew SOMEBODY would need them SOMEWHERE and SOMETIME!
