Atco Balmoral 17s - year/model identification

Hello all

I picked up a non-working Atco Balmoral 17s from a neighbour a few doors down about 2 years ago. He said he could no longer use it and was moving house so was happy to let it go for a very reasonable price (plus scarifier cassette). I'm not mechanically minded when it comes to engines, with bicycles being my main area of tinkering, but I managed to get it running with a carb clean, clean-up and new belts. I have been using it happily through the last year and sent the cylinder off to be refurbed and sharpened last Autumn. Now I'm looking to strip down, clean and replace more of the parts.

I'm curious about what model/year the mower is though. The model on mine is L80602...

Anyone know what year/model this corresponds to?

It seems models F016308042 and F016308242 are the models with the wooden front grooming rollers, as mine has, but there doesn't seem to be much mention of my model out there aside from F 016 L80 602 on https://www.powertoolspares.com/atco/lawnmower-balmoral-17s.m/f016l80602/spares

Thanks, Ben
