Well I think that is just all speculation as far as releasing something that may or may not be better looking.I can't see how that could be proven also I really don't think that would have been the thinking behind it.Besides we are really just trying to find out which model is which,not which one is the better looking mower.Sorry but I really don't want this post to off topic as I'd really like to know which is which model.I have a few of both versions and I really don't know what they are right now except for Victa's made in 1960 and 1961.As far as the engine with the MK9 and MK10 engines is the 10 is just the updated model.I don't think there is any difference it is just the next release.
