Hi
Does anyone on the forum know, have a ventilation disk or drawing for a S6 1930 according to photo. (photo from Ian Dabney)

Hello Kalle,

I found a drawing that I made from my very worn breather disc and estimated the dimensions from that. Also attached are some photos. Note that there is a ring around the disc with mesh wire holes in it - you can just see it in the photo of the assembled engine. You will have to make a bronze bush to suit the size of your shaft and press it in.

Good luck.

Bert
