Hello
Tjames1991 and
MaxI think I have a possible discovery here...
Model 350625This advert came from Geoff Nowak's photostream
https://www.flickr.com/photos/94854784@N06/22668088068/in/album-72157653492557023/Max, you were spot-on with dating.
The Mower number is the basic model [35] with serial number.
I do not understand why SB did not stamp model numbers
on their rotaries. They certainly did on many reel mowers.
Not a lot of decoding to do as no factory production records
from the period survive.
