how do i find date of manufacture of s11

How do I find the date of manufacture on my series 11 thanks

Try looking at gaydon heritage museum, they have records of every landrover made. You supply the chassis number and some other details and for £5 they will do a search.....

I used this service for my lightweight and the paperwork I paid for then allowed me to get a proper age related plate (1971) as opposed to a w reg when it came out of MOD
