I will put up some photos of the alloy base tonight, and i will check what other bases I can offer, and put them up to, then i will work out when I'm up your way next.
Rodeobob, I wouldn’t imagine a base being over 10kg, and most Victa 2-strokes are just over 30 kg, I do know that if you have damaged alloy bases to get rid of, stripping them down to just the base yourself can up the price you can get for them, often, if you completely strip an alloy base, you can trade it for a whole mower, as it saves them the effort, and puts it straight into the 'clean-alloy' pile.
