Quick qquestion - are the cross-screw for the mills 1903 front band and the stamped A3 front band the same part? If not, are they compatible?
I haven't got one of each handy to compare them, but the A3 screw I have does thread into the 1903 milled band I have, though the shaft end is a little loose-ish at the non-threaded end of the band. I can't recall if there is a milled band screw that has a tighter fit at the non-threaded end?
