3 Speed Gearbox With Neutral(manual)

this is a 3 speed manual gearbox it has slow, medium, fast, and neutral. It is very compact. I cant have instructions because it was built specifically for and built into a model I am working on. if you think you can replicate it just ask for some more pics and I will give them.

this is where the power goes.

to shift this all you need to do is move the Orange rod.
