Up for sale here is this box of 10 vintage Tung-Sol Miniature No 40 light bulbs. These are all brand new NOS bulbs, and will work great for you. These are some awesome and hard-to-find vintage bulbs.  The box does have some wear from storage/handling, and the bulb bases are tarnished/oxidized and may need polishing/cleaning.  Please see 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 many more bulbs and other vintage electronics listed--feel free to take a look!
