Great job on that mower.
On the front wheels, a man of your talents could regroove the front tyres. Not new, but looks almost like it and essentially free.
Not sure how you would actually do it but im sure you will work it out.
I picked up a victa a couple of weeks back, looking at the wheels i thought they were new. Having a closer looks someone has hand grooved them, a bit deeper than i would imagine the originals to have been done and not quite straight. I had to ask myself why, must have had some traction issues. lol.
Whats next, a little baby ride on???
Not being rude, you strike me as the kind of guy that likes to do it himself. Not sure about NZ but little ride ons pop up here all the time on eBay. You would do an awesome job of restoring one of them.
Cheers, Bob.
