ME 109g-6 u4 arnaments?

[George Hopp]

Would it be reasonable to assume - that from a documentation point of view - a maintenance depot or aircraft assembly works would dispatch aircraft to the front line listed as (e.g.) Bf109G-6/U4?

Any description involving the add-on rustsatz items, perhaps only appearing in unit combat reports; e.g. 14 aircraft sorties today - interception mission - 8x Bf109G-6/R6 and 6x Bf109G-6/U4, etc (as an example)?

My feeling on this would be that the maintenance depot or a/c assembly works would want to give the receiving unit as much data as possible on the a/c. So, if it had Rustsatz 1, it had the wiring for the ETC 500, but it didn't have the plumbing for the 300l drop tank. If it didn't have Rustsatz 7, it could only use the FuG 16 ZE radio, since the others had the homing facility. Etc.

And, in sortie reports, I would guess that the basic description, 109G-6, 109 G-6/U4, and even just 109G would be considered sufficient.

But, don't despair, geoff, I have been wrong before.
All the best,
