This is very relevant link, I've found it a week ago and got permission into archives yesterday. I found almost everything according internal structure of the fuselage (perfect 3D renders) and radio itself including exact type of radio. So if I would like to build fuselage without skin (only ribs), I have everything needed. There is also a picture of slightly opened radio hatch in the archives, and this helps a lot. But I don't have picture of internal side of cover panel, don't know the angle of fully opened cover panel and I don't know how edges of the "hole" in the fuselage look like. On other hand I have to admit, that at this moment it is acceptable for me to use a bit of "artistic" license and I will do it the same way as it's done for spitfire for example. But it would be lovely to have a picture anyway :-) Anyway, thank you for response :-)
