Hi, good morning:
Nice set of armoured vehicles! Specially your Verdeja!
Well, now again in my "comfort zone"
, but with a slightly more modern artillery: This is the German heavy howitzer Morser 18, a 210 mm caliber weapon, firing a useful HE 260 pounder round.
It was an useful weapon, very steady and precise thanks to a dual recoil system. Here is depicted as it was in the Western Front in May-June 1940, and in the dunkelgelb drab of 1943, during the Wehrmacht´s retreat in Ukraine. It was the basis for the 170 mm long range gun. Cheers.
Notes: The first model, the one in dunkelgrau, had a slightly modified non-historical wheels (I was unable to draw a decent 10 legs wheel
). My appologies.
I actually was trying for the longest time to find plans/other refrences to draw this beast, but I am so glad that you drew it instead. Beautiful work!
