Given the recent excellent Valentine kits, is it perhaps finally time for a Churchill? The existing Warlord/Italeri kit is decent, but precludes making either early (MkI or II 2pdr armed variants) or late (MkVII/VIII) versions.
The external hull appearance doesn't change dramatically across the marks (downward facing air-intake louvres give way to upward facing, the number of slats on the rear air intake increases, up-armoured sides to the track sponsons on the 'Heavy' MkVII/VIII etc.), with the main differences being the turrets (early small cast for the 2pdr, the welded and cast variants for the 6pdr armed tanks, the NA75 with its re-purposed Sherman 75mm & new cast turrets for the subsequent models).
It could probably be done with 2 different kits, covering the earlier and later models respectively - and since the Churchill should probably be regarded as the most significant British made tank of the war - in production for most of the conflict, serving in North Africa, the disastrous Dieppe landings, the ETO and in the East under lend-lease, it would seem that one is due - any chance?
