Hi Wazza...ahhhh...I was right....she is a Model 33 and number 7659 in the series.
Unfortunately, the serials don't relate to an exact date, but from her appearance, I would guess that she is an early one.
congrats it is a grand machine, and properly maintained will give you hours of mowing pleasure... wink
cheers2
