Re: Battery case links and scans.
The cheapest American made batteries of the early to mid 1920s attempted to use black pitch. There are only a few rare examples left. The manufacturing methods on your side of the Atlantic with sealed covers over the connections made the ugliness of the black pitch less of an issue at the point of sale. The Drydex graphics available to me seem to date from 1932. I wanted something earlier and so I went with the G.E.C. version which may well be atypical of the market there at the time. BUT since I was using an actual vintage artifact as reference, I had to stay true to the Red pitch scheme. I still don't have solid information from which to date my G.E.C. replica.
