Maybe what I looked at wasn't a BK2. It was the XXX Kinwald edition. The pivot block is the same # as the original XXX so it'd have to have the same spacing, right?
Looking at the parts explosion they thru bolted the pivot block and changed the material of the hinge pin brace to metal. I think the gearbox halves are the same #'s, too.
Yes. There is an XXX Kinwald edition that has the same configuration as the orignial XXX.
