Nice, thanks, worth to mention that the 23x115 ammunition used today is not exactly the same as in ww2. The primer is electrical in ignited the AM/ GSh designs not mechanical like in wartimes.
Other change was to reduce the projectile weight thus increasing muzzle velocity.
The Berezin UBT which sits prominently in the rear of the Il-2 seems to be poorly documented in books and on the web.
Every photo that I look at seems to be a different model or mounting and drawings are confusing. For example, I have a drawing of the Il-2 by Harry Woodman, who is usually pretty reliable, showing a cocking lever sitting vertically above the breech/feed area with another vertical handle on the left side, fitted with the trigger. The notes say that the weapon was aimed like a bazooka, with the gun sitting on the right shoulder and held there with the right hand holding a grip under the gun, the gun being fired via a trigger on the left side vertical grip.
Other drawings show a conventional pistol grip under the gun a la Lewis gun. Some show a simple pintle mounting and others show a tubular cradle.
These could be variations on a theme but can anyone clarify the situation for me? Unlike built in forward firing guns and cannon, this weapon is fully exposed and as it is fitted to the most produced aircraft of WW2, it surely deserves better documentation.
We fly a 1954 Yak C-11 which was originally fitted with a 12.7mm UBS Machine gun. We want to replicate three units for three Yaks flying in the UK. The 25kg replica will help restore the correct CofG point for the aircraft which is a bit to far aft at the moment. Do you have anything on the UBS that we could use to make the steel replicas? Ideally we need something dimensioned but with a good drawing or photographs I can back-calculate dimensions.
Thanks in advance,
John

Hi John,
I have not seen Charles online for a while. I don't have much info on Soviet weapons but give me a couple of days and see if I can dig any thing up unless Charles chimes in
