Basic weight of an A7 rolling chassis + engine etc

[AllAlloyCup]

Hi Mark
30kgseems about right for the tub
Floors , seat and trim might add another 5kg?

I see from Bryan Purves book that the all up
unladen weight of a Cup is 6.5cwt=728 lbs
Weight of an early Chummy of the same era
Is also quoted as 11 lbs per 10cc = 823 lbs

So a Cup is roughly 1cwt lighter than a Chummy
and 2 1/2 cwt lighter than an early Saloon.

So at least 10mph faster....?
