Well I've had some time to refine the top cell covers. There will only be slight tweaks from now on to these parts.
This is the first time I have added a preliminary label to the rendering.... Looks pretty good. You might notice that I placed the virtual lighting too far down on the right and there should have been more virtual light on the label. But since it takes me about a half hour to correct things like that, its not worth it for now.
Figuring out just how to get the lable near perfect has been more of a chore than I had thought it would be. As it turns out, there are subtle changes over time from when the battery was announced in 1929 and to where the A-600 was revised to the A-2600 in (I think) 1938. The fact that Geoff Bourne's cut-away model has the two pin socket in addition to the Fahnstock clips, makes it almost certain that our version dates from 1936/37.
Thursday I found three advertisements on eBay from 1934 that, while not featuring the battery, at least show it in color in a large enough image to give me more clues towards making it near perfect. Those are supposed to arrive around April 20th.
What these adverts show are paper labels on the side panels as well! While there is abundant evidence of a VERY difficult to remove adhesive on my case for the lable shown in the rendering, there is absolutely no evidence of adhesive residue on the side panels...
Hopefully I'll find some '36 to '38 vintage pictures that will confirm that the side labels were eliminated.
