NIB 4CX1000 tubes

[Opcom]

Two NIB 4CX1000 tubes. Original part for Collins 30S-1 and other equipment. $500 each.

One is still sealed in original carton dated 11/62 and the other one has been opened, also dated 11/62... It has never been plugged into anything but the silver plating has some tarnish spots. I guess those happen from looking at it. These are brand new not pulls or used. Money order or check is fine, no paypal, thanks. Shipping well packed by UPS or fedex ground.

Retail is $700 from RF Parts

Money goes directly to impoverished widow of SK estate, no lowballs to widow, I am posting this as a courtesy to help out and have no pecuniary involvement. Thanks.
