That's a very nice piece of work. I'm building my first replica Drydex grid bias battery, and I wonder how you made the very realistic-looking red 'pitch' coating to the top of the battery? Was it coloured epoxy resin? It looks most professional. I am using 4mm I/D brass tubing for the contacts.

Many thanks,
