The C10 is an excellent match pistol that came in two versions - high barrel and low barrel. http://bobsairguns.com/index.php?opt...lery&Itemid=42
Even the "high barrel" version is mounted lower than the Model 2 that it replaced (or the C20 that in turn replaced the C10) but both shoot the same as far as I can see and are probably worth the same as well - although the very low barrel types are nice and "quirky".
I have seen some tatty C10 pistols sell for very little but mint and boxed ones have sold for considerably more than your suggested asking price range.
Assuming the pistol and cylinders have no leaks and it shoot's well I would say that your suggested price range is about right for the condition you describe and would start by asking the higher value (£250) and see what interest you get.
Some photos would help to be more accurate with pricing advice so we could see the actual condition of the pistol.
