[Boatanchors] Any Interest? Adapter, Tube Socket MX-1417/U For Hickok 547

[William]

Hello All,
Had one of these in a recent bulk purchase.  Looks pretty clean, includes small tube data book and instructions.  Appears complete.
Case has a few nicks and scratches and the seal around the lid is starting to become unglued.  There is some corrosion on the aluminum binding screws used on the instruction book.

It will be shipped via USPS Standard Post in a 8x7x4 inch box, ship weight ~2.5 lbs, from ZIP Code 55076.
Is $20 plus postage reasonable?
Best Regards,
William
