These two pictures show my first 100% replica almost finished....  I've yet to add the two pin jack that replaced the Fahnstock Clips in the 1938 version. (Mine and Geoff's versions have the clips and the jack.)  I'll probably not have time to update these pages until late next month....  Still I think I'm going to be pleased with the results.
And, yes, the mold seams are supposed to be rough.  Remember, this was a one-time use battery with no salvagable materials.
That blue is supposed to be royal purple.
Already have done that color correction.
