It's rather a M36, not a M40.
This said, sorry to say but i do not think that this Feldbluse is an original one.
I could be wrong of course, no ones knows everything but in my opinion it is a reenactor's Feldbluse with repro Litzen and most probably repro Schulterklappen.
The quality of the wool, the nature of the lining, the fake markings with weird font, the buttons, the handmade buttonholes on the shoulderstraps and the Litzen....they all scream to me : CRAP....
