As far as I’m aware, Yamaha did not offer drums until they began in 1967. Those have the “Y” badge.
Around 197x (not sure of exact date), they switched to the rectangular badge attached by the vent grommet. That changed form slightly over the years (earlier had square corners on the bottom and a pink hue; later rounded all corners, later same shape but a pale gold color which continued into the divorce of Sakae when they went to the screwed on badges.)
Above for the “D” series; 9000 series and a recording Custom series. Those with 100% birch shells. Other lines had different badges, but the 8000/tour custom had similar badges at the same time.
If Yamaha dabbled before 1967, they did it without their name attached to the product. If they did, I would think the lugs would give them away. They never used re-rings either, and even the first D-20 kits had the angled ply seams.
