"Late commando frames with F&# stamped on frame neck."
Do any of you guys(or gals) have late frames with frame stampings that you can ALSO get a peak at the LH frme gusset behind the Z plate...
I have found imperial size tube frames with stamping such as R 275 (reynolds feb 1975)
and metric sized tube frames without that stamping.
only at the very end during nortons demise have I seen ONE that lost the full frame stamping including the "F".
I do not believe the F has any identification value to determine reynolds or italian.....imperial or metric tubing.
