The cuff stiching as Nick points out does have that very square appearance associated with Janke tunics.
Id disagree however that "squared" cuffs automatically indicate repro as study of period photos show a variation in styles.Some were tapered and some were rectangular but certainly not as blocky as the first pictured example.
I know this is a woolen tunic but the majority of HBT tunics of the M42 pattern i have encountered have rectangular not tapered cuffs.
Something wrong with the Croatian tunic, at least wrong length belt support tongues, with wrong count of the holes ( must be 4)
The liner is too fresh and I feel something wrong with the rayon itself. It's isn't look like a original " heavy" cloth to me
