I do enjoy the occasional surprise, but only one in my favor.
My battery case arrived today, and it's just brilliant.
I couldn't resist the by now fully expected 'trial fit'.
Fills the space beautifully.

The surprise came when I turned over the plastic top panel, which was shown on the ebay auction, looking like this....

..........and it looked like this on the other side. Cool!
I had been looking for a pair of the lead connectors, and now they found ME.

I originally thought that plastic piece would be something I would throw away, because it's not how the top should look. When I turned it over and saw the cell connecting lead bars, terminal felts, and cell caps WERE ALL THERE, I nearly fell down dead. I won't actually be using the cell caps. Have ordered a set with Ford script on them, but I will most certainly re-use the lead connectors, but not before I make a couple of plaster moulds from them though. Someone put a lot of effort into trying to fake a top cover for this battery. Unfortunately...........it's not convincing.
