Best grease for Wild Willy M38 gearbox

[Colibri]

I just got my hands on a WW M38 which I am restoring. I cleaned the gear box to day that was jamed packed with Vaseline? and would not let it turn. I have replaced the bushings with ballbearing as well. What would you say the best grease for this would be? Tamiya or any other make.

Personally i'd use Tamiya Ceramic Grease?
