Well I think it needs a lot of work

I need to revisit all my 109Es and most of my 109Fs and update them all. It's just very time consuming.
P.S. I'm still not sure of the significance of the markings. Not sure if tha was standard or if it was some special marking denoting a unit crest, or perhaps some royal crest... I placed it in time and I had photo references of it, so I went with it, but when I redo it I'm debating putting on standard boxes-with-crosses Bulgarian markings.
