I have finally got around to sorting the photos out, but thank you for your kind offer TC. It's not of the whole thing, I had already taken it apart before taking photos, but you get the idea of the condition. Usable, but a bit rough. Front roller isn't bent, just uncorrected optical distortion from my phone's camera.
Still haven't taken the rollers apart. Still undecided on that front. Main reason I want to disassemble is to clean and protect. Geraldton is subject to very strong seabreeze year round.
Thinking about going new chains, sprockets and carriers "while I'm there."
I don't collect mowers. I just require Multiple Mowing Solutions™.
