Hi He an old fox, be very careful, when I was building SL Lady Beatrice, I paid JH £575 up front for a boiler, 10 months later still no boiler,!!!! it take ages, to get a refund, and he took £75 off me for cancelling the order, !!!!, personal visit is the only answer, and make sure his wife is in, !!! he hates trouble when she's home, !!!
best of luck,
