My '53 100, has Body # 4360214, as I understand this, could be wrong,4360 is batch# &214 is car #. I know she's an early car(we call her baby)so from what I've read, she's about the 126th one made? could be wrong, other owners talk about different #'s,so that's why I'm a little confused. chassis is # 143703. Suppose I'll have to break down & get a Heritage Certificate for her& the other 2 cars. cheers Genos2
