I've called Chempix but nobody is in from that department until Monday so can't answer any queries. I'm away on holiday all next week so can't easily chase it up. G&H have been reasonably helpful, but they are also now closed until Monday! I'll wait to see what advice they give. I'm currently redrawing all the artwork in CAD and will account for all versions of both prototypes in those designs, including sectional resin bonnets too. I'm also currently in negotiations to add to the range, but more of that another time. I think most people realise what the shortfalls of these kits are – I certainly do – but I don't want to add to those oddities either. To answer your question, Steph, yes it's a whole production run. Thanks for the insights, advice and sympathies – all very much needed at the moment. At least I have a week in Devon to not think about it!
