These 52a lamps appear to be from the 1970's and 1980's.  Some have WE type quarter and date markings, some have red, some have yellow, some have green bases.  Let me know if you have a preference for the color of the base and I will send that color. Each bulb will be tested each for continuity upon shipping. I do not know if these are NOS or used.  They would have been used in keysets and switchboards with 18V to 24V transformers.  These come with free USPS boxed shipping and tracking. They have been stored and packaged smoke free.

North Carolina SALES TAX will be added.

For Domestic buyers, I am happy to offer combined shipping at USPS rates.  Please use your shopping cart after you commit to buy by auction or buy it now.  Then make sure to use the "request total" in the right upper corner of my seller's window in your cart.  Please wait for an invoice BEFORE paying to get a combined shipping discount.

For international buyers, I use ebay's Global Shipping program which uses a third- party shipper who offers combined shipping with restrictions. If you are an international buyer and buy multiple items, ebay will allow me to combine your purchases into one box for shipment ONLY if you wait to pay for all of your purchases at the same time using your shopping cart. Please note that Ebay uses the combined weights of all the individual items to calculate combined shipping. Unfortunately, Ebay will not allow me to offer any further discount on international shipping beyond the saving of shipping one package.



We pack up an mail items on Fridays and Saturdays. Depending on timing of purchase and your payment, handling time will be 1 to 7 days
