It is a Moss box an HR in fact it turns out,
We communicate on Whatsapp and one question he has is what is the gauge of the metal on the car ? obviously this vintage on an untampered with car such as this it's all steel.
.
Great , I think all +8s had the HR Moss Box , (as did most of the last of the +4s) Others might know of the changeover date?
As regards the metal gauge I assume you are talking about the chassis rather than the body panels?
If so I am not sure I have the figure off the top of my head (others might?) but THE expert here is Terry Foxen at GEE. He can supply "new" chassis of good quality and finished really nicely.
In the days when I raced , some folk rebuilt their Mogs onto a lighter gauge chassis in order to save weight (flexing is not too much of an issue on a track car) David Rutherford was the best known proponent of this way of thinking. Some owners who competed in the Lands End trials type of events went the opposite way and built them up on a chassis that was one gauge thicker, and were prepared to accept the weight penalty.
