I'm not conversant with production methods but would have thought it logical to make use of existing arrangements. That would give lots of options for German vehicles.
The panzer iv base could be adapted to a Stug or Jagdpanzer for example.
As a business there is the possibility of collaboration with other 1/6 makers in the UK. I've seen a churchill on offer that didn't seem to go into full production. Perhaps that might be picked up.
From what I've seen so far Matilda and universal carrier seem popular. They get a thumbs up from me.
I'm going for Panzer 4 revival & US Half track. Both already in the system so basically re-runs which would fulfill the summer dispatch. Also cheaper therefore catering to those loving the brand but out priced with the larger releases. Possibly the sherman instead of the half track.
I'm wondering if perhaps we could have a Churchill or Cromwell on our hands. Airfix have just announced a Cromwell for summer release, their first new tool large armour kit in decades. I'd love to think of two of my favourite companies working together....Armortek does have prior form with the Comet.
