While we may never know for sure, I do think due consideration should be given to another photograph of General Grabmann holding a 2nd model dagger. Look at the size of the pommel (and dagger) in relation to his hand. Does it look like he has small hands??
Also, a round/spheroid pommel like that on a 2nd model would tend to show that kind of a reflected light pattern. And in the preceding photograph it does not look like Breves has particularly small hands either, although they might not be quite as large as the General�s. FP
