Thanks all for the advice, on balance it looks as if the long-handle jobs are the way to go and I expect to take up Mr Gazza's kind offer shortly, the local cake shop has offered to open up it's Brexit stockpile warehouse.

Darren69 - thanks for adding the photo, looks just same clearance as mine. It steers well enough, so I reckon it is probably factory, I will leave as is until the important jobs are done.
Cheers
