Up for sale here is this lot of 2 NOS vintage unused brown 7-pin tube sockets. These are marked "312," so I believe they were made by Sylvania. They have J-slot mounts for covers (not included) and have frilly copper rings around them, possibly for grounding. Please take a close look at my pictures for details.

US shipping and handling is $5, and international is $18, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. If you have any questions, please ask.

I have a number of other sockets, collectibles, Magic cards, and vintage electronics listed--feel free to take a look!
