Alright, while I was at it, I did a very quick "how I do it" to make a standoff gun for the Lancaster.
I used stuff I had in the workshop, scrap wood and metal.
The main part of the gun is made with 10x10 Balsa.
The barrel are made of Stainless steel tubes, cut to size.
The overall length is about 100mm
Add to that a few pieces of wood to make the handle and the loader (?), and you have something that look decent from a distance
Photos are self explanatory
Tonight, painting and weathering
