Need help on this swedish overcoat

[frei]

I am not sure where to post this since sweden was a neutral country in ww2.
I found this overcoat last week and I am not sure what it is.
This one is grey and not green as I know them.
Can anyone help me out ? I am no expert in swedish military.

Maybe air force? Here's a colour comparison.

I pretty sure those buttons are Norwegian.

I agree-looks like Norwegian Air Force to me as well. Swedish would have the 3 crowns on them.

Thanks, I took a better look at the bottoms and on the backside it is stamped (hard to see) something like ''cornelius Oslo''.
Then it must be Norwegian army !
Again thanks a lot for your help.
