Great stuff again Gary, and looking at the interior of the ball turret, really brings things home. Not only cramped, claustrophobic but vertigo inducing, the gunner had a Fifty Cal blatting off in each lug hole !!
BTW, if you decide to go for a Jeep, let me know, as I think I still have a contact for ex-French Army/Air Force Hotchkiss versions, at good prices - outwardly almost the same, but with 'modern' running gear, brakes etc.
