Thanks, Jack.
having spent a # of fruitless hours in the shed today, it is slowly coming apart, but I am hesitant to do too much until I know where I'm going with it.
It looks to me like an early attempt at political correctness & like the modern version, is completely wrong
Your manuals should be of great benefit
A couple of numbers came to light as I stripped bits off & you are correct (again) it is model 430 and machine # 1006
It is in surprisingly good nick as far as blades & general condition are concerned & the engine appears to be okay too.
Shall keep you up to speed, but it will be slow going I think.
Cheers & many thanks
