• @general_greyharbour Never seen a Panasonic like that, they use a cast lug integrating the binding bolt (photo below), this is separate pieces brazed together. Also Panasonics always have their spikey headlugs. But the dropouts look similar.

    3rensho built this style occasionally. And then so did his co-workers sometimes when they went their separate ways - Makino and Yamaguchi.

    Certainly I've seen a few Makino that way and it would be my first choice except for the rear dropouts aren't normally the same, and they'd use more standard short-point lugs where 3rensho might not have (like in the long-point example below). 3rensho would use a similar rear dropout (shown below).

    There's one other too I'm trying to dig out but they did it slightly differently with a smoother top edge across the lug and seat-stays.

  • Brilliant insights!
    Thank you!

    I had a Makino a few years ago - HERE ON PEDALROOM
    It had a similar seat stay arrangement but by comparison, the dropouts were much simpler than on this unidentified frameset.

    I have a bunch of decent parts-bin stuff to build it up but it won't be respectful to a proper NJS build 'cause I don't wanna buy new parts!

    I can paint to a high standard so the finish will be "fun" in some way... my only aim really is to try and find out which logo should be painting on it!

    Panasonic is great but compared to others, the logo is a yawn.
    I've never seen a Makino I didn't like.
    I LOVE that chunky Yamaguchi logotype... if I've no way to get any kind of firm-ish answer, I think I'll just misspell the brand as "YAMAGUCCI" and call it a day.
