Hi Ron,
Sadly, no. All I've got are a couple of No.5 and a couple of the Panel, Power Distribution, No.8 from the Larkspur era. (Intended for larger vehicles than the Land Rovers people try to fit them in, then wonder why there's no room for the radio kit! Minimum vehicle is the Humber Pig, I think.)
You've made a wonderful job of that panel and the battery boxes; truly a Work of Craft.
Best regards (and I'll keep looking for the original items, just in case),
Chris.
