    We love when people show interest in our kits; it means people are building things again, and that makes us happy! Although we would like to have inventory of all our kits, it's often difficult to achieve due to fluctuating demands aligned with our manufacturing capabilities. We are only a small business, so we apologize in advance if your kit is not in stock when you place your order. However, we assure you we will get it done in a timely manner. 

    Kind Regards, 

    Peter Goldsmith
