Hope these help! Note, the curved plate in the kit is the top one, above the pipes. The one below it wasn't always fitted, or got lost, and the slatted arrangement on the third pic was added later. Tanks are, the Crab at Bovington, Crab at Overloon, and Firefly at Bovington respectively. The tube and cable in the last pic is a light for the engine bay, for when the doors are open.
OK, I'll admit it, I ran out of room on the etched brass sheet! Easy things to knock up from thin aluminium foil, plastic sheet or brass if you need them.
