Rosco, have you sorted this out yet, the huskyclub.com site reveals that your weapon, with eng no beginning with 2026, is in fact a 1973 250 WR/RT. The CR250 eng no begins with 2028, and the WR with 2032. So yours is/was a road/trail with stainless guards, originally had lights ( or if not, should be fitted with lighting coils in the ignition ), and was most likely fitted with an Amal carb. Should be plenty of info about, but quite a rare bird all the same, enjoy your quest !
