Blumbly, whats the difference between the Model 12 Utility base and the 1963-64 Utility Model 509 base? also what year is a Model 12? Is it the V35 (Victa code) 65-67? Got heaps of other questions on some of the others I got today also but will do a bit by bit so you dont get sick of me. I ended up bringing home 15 mowers, 7 of them are the ones you have already identified for me though, and 3 others I know are two more model 5 series 1 and the other is a series 2, so that just leaves 5.
Bugger you've got me worried now I can't find my model 12 base.I'll have another tomorrow.The different's really is only the bar that runs across the deck on the 509 is wider (or taller) than the model 12.I guess it's like the thickness of the model 8 for the model 12 where as the 509 is almost twice the size.Also the axle mounts were different,model 12 sort of had.Like this picture.

I know this is a model 8 but the 12 had the same axles.Where as the 509 had this type.
I can't remember but I think that's the only difference between them.The 509 has a guard at the back of the base but that's just a bolt on thing.Not really to do with the base.
The Model 12 was made in 1962-63.The Victacode V35 is actually for the 1965-67 Utility Model 530. Also don't worry about the questions it's the only way we can learn about what we love to do.So keep them coming.
