Hi guys,
Not left the house at all, just in shock we have another LP owner!! and one that's going lol

You've certainly got yourself a beauty there Vmow!!

AS I know things, the BMS engines were produced in house after the JAP engines were dropped. This would make it 1957 as to the addition of height adjustment.

I know mines a '56 with a '55 JAP 80C engine. Seized to buggery and no height control.

Cut will be 18" unless you have the CUB which I think was also introduced in '56 / '57 with a 15" cut.

There was also a Scout, but unsure if this was a rebadging of the older 18" Lawn Patrols or different size again.
