Unfortunately the Airfix of today is NOT the Airfix we knew in the 1970s. The guys who developed the Multipose figures, the 1/32nd scale kits, the styrene 54mm figures and the soft plastic figures have all since retired or moved on. Airfix has gone through some rough times and several corporate ownerships. Despite what we on this list think, 1/32nd military models are a small marginal market (although 1/32 kits remain popular in aircraft). Airfix might continue to reissue some older kits as "memorabilia" but I don't think we will see them pursue 1/32nd military with any vigor.
Speaking of Airfix, weren't they supposed to reissue the 17-pounder gun in 1/32nd in 2015? I thought I remembered a rumor about that.
