Any ideas regarding manufacturer/vintage?

Judging by the pickups it looks to have been made in Japan in the late 1960's. It's likely the same company that made Teisco/Norma/Kingston/Guyatone etc. guitars. Seems to be in good shape and those super hot pickups usually have a pretty unique sound.

Someone posted asking about a guitar with seemingly identical pickups within the last week or so. The guitar is different, but that might help.

I'm a little late to the party, but u/lawn_glossed nailed it on his comment. To go further, you can check out [this site] (https://drowninginguitars.com/2012/06/29/the-bizarre-guitar-pickup-encyclopedia/) that has a lot of pictures of pickups found in those likely Japanese made guitars. The pictures are accompanied by models and winding ratings that may help you cross reference across other sites when searching. Sweet axe regardless. Rip it up.

I've got an Aria L5 copy from the 70s with the same logo on the head stock. Perhaps it's an Aria? Definitley a Japanese guitar.
