WTD - 1/72 or 1/76 Tank tracks

[Bungle]

 Hi,

I'm working on a few What-if vehicles in 1/72 and including converting wheeled vehicles to tracked. So I'm now after any spare tank tracks in 1/72 or 1/76 scale and/or any scrap tanks or other tracked vehicles (with separate tracks rather than moulded units) anyone wants to dispose of.

Willing to pay cash and postage for any items. Probably best if we leave it to the UK only but make me an offer I can't refuse and I'll... err... not refuse it.

Thanks in advance

Andy
