Ok, I looked over the jacket I am working on several times. I have to back off from saying there is no cutaway. The sporran cutaway is in a different, and lower, place than on my corduroy jacket mostly because the front of the jacket hangs diffrently.

On the corduroy jacket I converted, the curve of the cutaway is higher and the front of the jacket does not hang open quite as much as on this jacket. The corduroy jacket has a tapered section of the hem after the curve, this jacket is open enough that that raised curve isn't needed.

I was just confused by the different hang of the front of the jacket.

I still think it would look better with a third button between the two that are already there. These buttonholes are keyhole shaped, so I will have to practice making those kind of buttonholes if I go down the three button path.
