Really heavy shell for that bore- over twice standard, plus a relatively high MV. This could explain why you allocated higher than normal weight for a 105mm range gun. I believe firing platform with 360 traverse is a generation early, not certain. While there were AA platforms with outriggers, the wheel up, platform down, very widely split tail strongly resembles a smaller 122mm D-30, which was somewhat known for that.

1. Skoda designed something like this in 1937. It was rejected as too radical.
2. I merely assume Siam would dust it off and try.
3. Heavy shell is a long skinny shell with lots of explosive filler. I want a large grenade going downrange in a jungle gun when I fight a jungle war.
4. Ballistically I wind up with a high MV because the shell ogive is not efficient. Drag is going to cut range dramatically. On the other hand SMASH is outstanding. This shell will arrive with all the joy of a lightweight 6 inch dropping in to say hello..

A bit early, the Picture shows the mock up for the 105mm leFH 43 (model Krupp), there was also the Model Skoda on which many delive the 122mm D-30 got its inspiration.

You're limited to a length of about 4-5 calibres before the shell isn't able to be stabilised by the barrel rifling. I'm pretty sure the only way to get that weight is by making the entire thing from lead. A larger calibre weapon with lower mv might be more useful in the enclosed jungle terrain - just need some airbursting shells...

Actually at 7.2 grams per cubic mm a shell 100 mm x 900 mm with an ogive of 0.8, as solid iron would be about 47.5 kilograms. Using aluminum boosted PBX filler and a blast/frag steel case [thinner but heavier] you get around 44.8 kg with 10% filler by volume.

Google books
Cannot find any pictures of it however.
