You probably need to specify the rig height, measured between sheerline & upper band on the mast. In those days rigs were referred to by this measurement in feet, to the nearest 6 inches, so rigs were 21', 21'6", 22' etc. Tolerance on lower band height w.r.t. sheerline was smaller then, so practically speaking the measurement above determines the luff length. Hope this helps.
