Is the trade mark on these the small one and close to the crossguard as on SS Rohms which have the SS motto ending 35mm from the crossguard rather than 25mm standard placement?
I wonder if the wax template was made in one piece for both sides of the blade and folded at the pointed end that would explain the 10 mm shift of the SS motto as the trademark moved 10mm nearer the crossguard on the reverse
