Going through some of the W5# gearbox I have,
as I just aquired another few,
W5# series box with the following ratio's?
1st = 3.954
2nd = 2.142
3rd = 1.385
4th = 1.000
5th = 0.850
Seems a strange one as I have a lot of the W55's and a W57,
but the teeth count on this one is really weird.
Even counted them multiple times to be sure?
