KV-75 project. Year?

[Roanokemassey]

Hi, I just got a new project.
I think it's a KV75.
Number stamped in frame below handle bars is MT-046942.
It's missing the coil, spark plug wire and spark plug.
It's spins free, so I need to get spark next.
Have carb off and soaking.
I need the year so I can get the right coil.
Thanks
