Size of 3-pounder gun barrel in 1/48 scale

[captain_hook]

Hello everyone,

 

may anyone help me please. I’m going to build a 1/48 scale british revenue cutter and having trouble to identify the correct size of a 3-pounder gun. Most scale guns seem to be oversized. I remember a 3-pounder gun having a gun barrel length of about 5‘ , is that correct? That would be about 30mm for the correct size of a scale 3-pounder barrel in 1/48 scale - equal to a 6-pounder gun barrel in 1/64 scale.

Assuming your model is late 18th century and British, a 3-pounder was typically 4' 6" long. At 1:48 scale (and in metric!) that would be about 28mm.

From Lavery " The Arming and Fitting of English Ships of War 1600-1815" " The eighteenth century 3-pounder was between 4ft 6in and 6ft long". Using 5ft my math indicates between 32 and 33 mm so 30mm should be fine.

Thank you very much for the fast replies. That is very helpful.

Hello Captain Hook,

 

I made a compilation of gun sizes ( Armstrong Frederick-Design ) of 1760. Dimensions in Imperial and conversion into metric.

Some details of carriages ( also in German language) from various sources as well. All in a xls sheet. I will try to turn the 3 -pounders on my small Unimat-3 lathe.

I'll inform about results later. I'm working on Af Chapman English cutter.
