Came across a good image of the 38cm sehr schwere Minenwerfer in the sludge pond (internet).
It certainly was a beast - I think Arie said there were only 3 built due to barrel explosions.

Now that would make a good model in 1/72nd scale Grant
The front view is from the book "50 Jahre Rheinmetall Düsseldorf 1889-1939" - part of it is on Google books.
According to the text the mortar was 40cm calibre and first developed in 1909. The text goes on to say this is
suspect since the 25cm Minenwerfer wasn't developed until 1911. There are differences between the 40cm and 38cm
Minenwerfers but the basic idea is the same.
I looked up the 2010 post - Arie said there were two deployed to the Voges in 1916 - both expired with barrel explosions.
The heavy 38cm projectile was 400 kg - max. range 400m - sounds a bit like the Davy Crocket nuclear recoilless rifle - the gun crew
was inside the lethal radius of the weapon.
