Hello Greg, everybody!
Thanks a lot for your kind words - and it's been almost exactly a year ago since I wrote here so Im sorry for letting you wait so long...
The last year has not been easy for many of us, and I was also a bit stuck with one detail of this model here - the rear gun. While this model has more than one weak spot I think the gun is most seriously effed up and if you know me you know I had a hard time living with that - I just had to fix it. As you will se it meant almost building the gun from scratch.
So here's what the gun is supposed to look like:
We're talking Berezin UB 12,7mm machine gun here - and I tell you it's pretty hard to get a good picture of that mount, and of course there are variations - the early guns were cocked manually and the later guns had a compressed air cylinder to do that (U in UB stands for universal meaning the gun can be mounted in wings or in a flexible mount).
The UB is said to have a big punch but being a relatively crude, throw-away weapon. It is therefore surprising for me to find out the rear mount in an Il-2 had a reflex sight for the rear gunner (I expected something more along the lines of two pieces of metal welded on to be lined up)
OK, so the model gives you a paper box to start with and you are supposed to make the barrel and the gas tube out of rolled paper. That doesn't work so well for small tubes. If you want to stick with paper you have to roll the tubes out of much thinner paper, but I just made the parts out of wire:
Then I started adding parts and correcting the kit's errors:
There's the gun mount made out of kit parts, but soon after I started researching I had to scrap it and make my own. In real life there's a curved rail along the edge of the opening where the gunner sits and a small bogey moves along the rail - and the gun itself is flexibly mounted to the bogey. This gives the gunner a lot better field of fire and an ability to shoot straight to the rear without hitting the tail, or to hit ground targets under the aircraft.
On the photo below I fabricated the rail and the bogey out of paper and I have added parts for the ammo feed and gun mount with the reflex sight. You can also see the kit supplied ammo box, which is basically OK, but the ammo chute has to be attached to it differently than the kit instructions say. As you see I started painting the parts:
And fast forward to yesterday when I took my man up pills and like Johnny Cash said "well up to then my plan went all right till we tried to put it all together one night". Here's the result:
I hope you like it and the biggest burden is now off my chest - so I hope I can finish this model this year :-)
Thanks for looking and have a nice day
