Hi Dave
Thanks for Your review which gave me a few points I should consider as soon as I'm going to build my 17 cm Kanone, which is essentially the same gun with the exception of the smaller caliber.
I also read your introduction with interest, but I have some objections to make in respect of the used tractors. First, I don't know what You want with the Mörserzugmittel, basically a Skoda 35(t) without turret weighing less than ten tons which could therefore tow about the same load as the eight ton halftrack Sdkfz 7.
The 21 cm Mörser was heavier than 22 tons assembled. As far as I can say that's why the Germans had at least one 18 ton Famo Halftrack in the heavy artillery batteries to move the three assembled guns of the Battery from the rearward assembly positions into the firing positions. The Sdkfz 7 were used for towing the gun tubes on their trolleys and the 12 ton Halftracks (Sdkfz.

for towing the gun carriages. Of course You could tow an assembled Gun with three Sdkfz. 7 or with two Sdkfz. 8 but this was quite a delicate matter even for experienced drivers and nearly an impossible task while trying to pull a gun into position with a compsiton between 30 to 40 meters (about 90 to 120 feet) in length on heavy ground.
I know, there were heavy batteries which used turretless 38 (t) tanks as prime movers for towing their 15 cm s FH 18 but that was an intermediate solution and the sFH 18 was a considerably lighter gun compared to the 21 cm Mörser.
However, Your review helped me to discover a few important things like the thickness of the springs on the lower carriage and the number of the jacks needed to hoist the gun I didn't care about before.
