Luftwaffe service tunic waffenrock - ask for help

[mike1]

Hi guys,
I would like to ask you for help with this Luftwaffe nco service tunic. I would like to know if the tunic is original one or fake. Before I posted this thread I have checked some tunics and here is what I have found, but I am not expert: I personally believe that the tunic itself is original piece for officer but used, what was not uncommon, by nco officer. Collar tabs looks for me originally applied, but eagle is hand stitched and shoulder boards are in my opinion bad ones, (maybe field made, but in that case everything could be marked as field made), loops for shoulder boards are also added, but I found that some soldiers did it for better tunic cleaning ( to have removable shlouder boards). In the inside of the tunic there is no maker mark, only some stamps which are not readable, only numbers 403 on the right one. Everything is uv negative.
Am I right?
Any opinion is welcome. Thank you,
Mike
