Is there evidence that there the distances bethween the two "nutfingers" were standardised in one area or at least at one town? Does someone know about the distance bethween the nutfingers of the crossbows in Hermannsstadt?
I 'think' at least towns, maybe even regions, must have had some standards for a lot of military stuff including distance between nut fingers.
I think that Josef Alm mentions this in his book, someone in a 15th c German town gets an order to trim crossbow bolts so they fit between nut fingers.
The Hermannstadt crossbows are a very interesting group of crossbows as they are said to all be an old Zeughaus inventory, and if that's correct, they will be military weapons and should probably have the same distance between the nut fingers.
