That's great. This is not my mower, but will be on display at the Balaklava Show next weekend along with my collection of Scott Bonnar mowers, so it is good to know of the SB link
G'day, I am in the process of restoring one( all be it a drawn out process). When blasting back the frame I found what looks to be a manufacture number of 133. If I can help in any way let me know. Ben
