our former member Heinz (Vulcan32) contacted me by phone yesterday. he always had and still has a very good contact to HPH. he asked me to post that HPH was considering a 32nd scale B-52, they would have to sell 100 kits at a price of 1200$.
if interrested, send them a mail or post here.
I don't know any of the details. HPH used fiberglass because of the cost of injection molding and it allows for a strong, thin shell. Resin would be even thicker and not structurally sound anywhere close to a scale shape. Both Plastic and Resin would lead to serious inaccuracies with the finished model shape and/or interior details. All I Know is I have seen 3D printed parts for most of the interior and one engine and that it is not GT Resin.
