Can anyone identify which model of 70s Yamaha this speedo is meant for?

I recently bought a little 2 stroke tiddler and this NOS speedo was in the box. It's too large for the bike I bought, so I would like to identify which bike it's meant for so I can sell it to someone who can use it in their restoration. It is very similar to the speedometer that was on my dad's 1973 DT360. However I know these parts are not universal to multiple models over different years. via /r/CafeRacers https://www.reddit.com/r/CafeRacers/comments/97jr7b/can_anyone_identify_which_model_of_70s_yamaha/?utm_source=ifttt
