2/18/2021 -- NOS specimen from 1974 measured by Karl. 3/8" 26tpi axle threading. Center of axle to center of reaction arm hole is about 78.5mm. Flanges are 2mm thick and spoke holes have no chamfering. Plastic oil cap on this specimen. Locknut to driver flange is 17mm. Looks like this takes a 1/8" cog and two 1/6" spacers to adjust chainline, just like most vintage 3spd SA hubs. Weight of 918g is the bare hub weighed with no axle nuts or cog or loose hardware of any type. -Karl
