Hey everyone just got two Westinghouse OV-25 silverliners from eBay today. One of them has a data sticker and the other one does not. I’m trying to figure out the dates of these beautiful lights. The one that has a label says M.F. But right after that it’s all washed away. Any way I would be able to figure out the date code without the data sticker? Any help would be appreciated!!

Check your capacitor(s) ! There should be a date code stamped on the capacitor body EXAMPLE : 74-40 is the 40th week of 1974 . If you can't decipher it just post a photo of the writing on the cap(s) and someone should be able to figure it out . 

Ok. I will be posting a picture of them both shortly. Stay tuned. Thanks

Here is the capacitor

If anyone could figure out if there is a date code on that It would be so appreciated!

MF is December 1972.

Wow thanks I’ll try and see what the other one is. But would you be able to explain how you found it?

MF is December 1972.
