Chassis Numbers.

I am selling a 1991 Defender 110. Yesterday I had a viewing and the viewer wanted to establish if the chassis was the original one. After scraping away the paint and underseal off the chassis at the offside front under the wing just behind the bumper he found the chassis number which matched the one on the plate on the servo.
My question is are there any other chassis numbers stamped anywhere on the chassis please.
Thanks.

no thats it,if number doesnt look like its been messed with you have a honest truck
