The tunic looks okay to me but I would think twice about the wear on the item as there are plenty good flieger blouses available if you shop around.
Real tunic. If you could get it for $800 or less in US dollars you would be doing okay. Bochmann is right in saying there are a lot of these on the market with less condition issues.
Agreed, a good original tunic. The only issue is the moth tracking.
