Someone was recently looking for complex molding planes. The e-bay seller honestjohn36 (search on seller) has a number of them for auction at present. I have bought molding planes from him and highly recommend him as someone who knows planes and knows how to sell them. Look at the pictures of any of his planes for an example. The shipping cost from the UK to the US is a bit steep, but you get excellent value for your money.
