Series 1 107

May be stamped on nearside rear spring anchor point, that's above front end of back spring on outside of chassis. I remember an 86" with it there, about the same age. Earlier ones were stamped above back end of rear nearside spring and 80" on top of nearside chassis engine mounting IIRC but I may be wrong.

Series One club chaps will tell you. Look for any repaired sections of chassis, it'll be under the repair.
