You can often find plenty of Rover mowers with non worn out wheels on them because the Briggs has given up the ghost, cut the spindles off and weld them onto your Victa. A question to ask yourself, how many of these over 60 year old neglected Victas are pulled out of the back of a shed, bit of a carby clean and they fire straight up and capable of being put straight back to work. You don't see too many 4 strokes capable of that
