thank you for the pictures
had been trying to puzzle out the connection between "nervous legs" and a mystery bicycle frame
yes, this is the lug pattern was thinking of
we are clearly in the early seventies here
seems odd from a modern perspective to see a frame with forged ends, dropout adjusters and chromed lugs which exhibits a welded crown
perhaps Japan did not have any forged crowns at this time
suspect the seat stay treatment might be telling if we could get a better view of it...
find it refreshing that the person who did the respray did not succumb to "braze-on fever" - clips work just fine
