Thanks for the review!

It's a quite large dimensional discrepancy for a relatively short barrel I think.

Would be interested to know RB Model's answer, they possibly used innacurate line drawings or dimensions? I don't think there would be different versions of the gun with different dimensions, or maybe a badly restored gun was used as reference?

Inquiring minds want to know!

Cheers,

Christophe

For some reason, if I remember correctly, that is what the Dragon 25 pdr was off by too. Maybe they used the same drawings?

You can see from the included pictures where my measurements came from and not everyone would have that opportunity. I have said there may be differences as I have no way of knowing if guns around the world have slight changes dimension wise. If there is one thing I have learnt it is to never say" That would never happen" as someone else on the site will post up a picture top prove otherwise.

Darren, you are probably pretty safe. I believe the tolerances for 25 pounders were reasonably tightly controlled, insert the usual apocryphal tale of being able to assemble a working breech block and ring from parts made in different countries.

There are some additional measurements here. Plates on that gun were General Motors Holdens, from memory.

I am taking some better pictures of this portion of the gun barrel to send to RB Model should they wish to refine the barrel. I will also seend them images of the barrel from the version minus the muzzle brake should they wish to make one available.
