There has been discussion here before regarding the chassis number (or car number as Morris Motors called it) which is found on an aluminium plate screwed onto the engine bay bulkhead and prefixed by a few letters which signify the model. This number is the one which is recorded on the registration document and in modern lingo is often refered to as a VIN number.
On the Morris Minor and 1000 this number is also found stamped into the body. Originally this was also on the engine bay bulkhead but after around 1965 the stamping moved to the driver's footwell where rust and repairs have sometimes destroyed it unfortunately.
I thought it might be helpful to show these positions for those who want to check their cars or indeed check a car offered for sale and in a recent idle moment photographed 2 Minor 1000s to demonstrate.
This first photo shows a 1965 car which is possibly one of the last to have used this position under the bonnet. If your car is this age or older it should be possible to see this.
