US 14" 50 Cal railway guns

[EPOCH3]

One nice thing about starting with digital models is that you can do what if scenarios.
Here are 3 of the 4 railway guns that used the 14" 50 Cal gun. On the left is the 14" MK I
designed and built in a just a few months and fielded by the Navy in France
during WWI. The military wanted to get away from having to dig prepared firing
pits as much as possible so they moved the gun up resulting in the MK II (middle).
The 14" design evolved into one of the best large caliber coastal artillery pieces
ever built with the 14" Model 1920 (also referred to as MKIII). This is the one of the guns
that would have met the Japanese or Germans had they gotten close to the Panama canal.
I plan to do all of these in 1/35th scale to go with my 14" Model E that I have already built. I would
have included the Model E in my rendering but it crashed my PC last time I tried to
do all four (so 3 of 4 for now). Only 96 wheels to go

For reference, here is the 14" Model E in 1/35th scale (posted elsewhere as well).
There was also A 5th design the would have also used the 14" 50 Cal that was a joint
design between the US and the French that was not built by the time the war ended.

I digitized on book on USN railway guns in WWI, should be available on history.navy.mil if you're interested.

Just a step 1 pic of the initial assembly for 14" Mk II carriage frame.
Frame was laser cut. Rivets are next - did I say lots of rivets
