I have just reallized you are asking for a 1/10 scale model of this gun. That is a big model for a Model engineer to take on with a home workshop.

Going back on the cost, I can see this costing upwards of £15000 and a time scale of 6 months or more at full time working. To create this model will require extensive research and much dedication, even a hands on look at the real thing if there is one with known whereabouts. At this scale everything will have to work, elevating mech. and the recuperators and of course the Breech mechanism. To create the locking breech will require gear work.

JasonB's assessment of the wheels alone needs large machine tools and access to a hearth or rolling machines of heavy duty type.

Hi thank you for your comments. My estimation is not a million miles from the suggested one. I will post pics of my tanks and other me models. And this is for me not a sub contract. I no longer do it for a living.

Oh I nearly forgot, I have my man. A retired toolmaker and ME enthusiast

I understand that most if you are geared for hobby work and this kind of project would be as huge as you say. But its not as big as that if you have the right machines I'm sure

There are only 3 moving parts. Elevation, breach, wheels + the crank handles and gears This guy is a professional model maker by commission and makes a very good living from it. I have 2 jobs by him already.

I've seen models by professional maker Anthony Walshaw that are of a greater size and complexity than you are looking for. He seems to be almost google proof, as Tony or Anthony.

Jason,

Outstanding. I couldn't make a single part to that standard

If he entered that in the ME Exhibition they'd have to give him a platinum medal... a guaranteed DoE Trophy winner. I'm not aware of any bar on professional entries, but I guess he chooses not to enter.
