Schumacher items

Hi

just a few items from a kit box someone passed to me (I didn't get the pro cat :/)

couple of pit stands on with pinions attached, 2 spurs instructions for a wasp replacement gearbox for a pro-cat, gear ratio charts. some shock towers (I don't know if they are original or hop ups I guess the former as it was raced) a can of tyre traction aan cleaning fluid (I don't know what this is just thought it might have some vintage appeal).

would rather sell the lot to a Schumacher

don't know what these are worth if anything

just send me an offer

postage uk @ cost I will get it priced (£3-4 max)
