Morris Minor Owners Club

One of the reasons I bought a Minor was the fact that my father had three in the late fifties and throughout the sixties.
Can anyone tell me when his first minor would have been registered ie 1958 or 1959 ? The registration was 8783 WB.
(A Sheffield registration)
Thanks.

If you knew the chassis no. there would be no problem. The reg no is not on the dvla database, it is possible that Sheffield still has the records in its archives but most authorities ditched them when the DVLA took over
