Nissan/Touhstsu model 3.5. 2 stroke

[Finalphase1]

I am hoping that someone here can id my Nissan 3.5 outboard motor. The model # tag is worn off and I need to put a piston and ring in it.
This motor is the Nissan 3.5 HP
2 stroke
Short shaft model
It has no mitral or reverse, ya just spin it around for reverse
It is one of the early ones it has breaker points
It is Dark Blue

Does any of this add up to a certain model ?

It's a 3.5A or A2. Good luck finding points.
