Yes I do sort of agree,although I class collectables as something that can be achieved.Lets face it Billy-carts and both fan mowers are extremely hard to get and if you did find them you would want to have a big wallet.Where as the Model 1 & 2 Rotomo's are achievable as well as the Model 4 Automatic.The Billy-carts and Fan mowers would be the most wanted (Hey I'd love at least one of each).So in that out look I'd say the model 1 & 2 Rotomo's and the model 4 automatic.Also as Bluegmhtmonaro said when it comes to non-victa's it does come down to personal choice.Me personally I love Scott Bonnar rotary's,but they are also hard to find.As I'm know finding out very hard to get much information about them.I'll just keep on trying.I also believe the most popular collectable would be all 3 series of the Model 5.I guess in mower & non-mower circles it would be the most iconic mower in Australia.They can spark up many conversations.
