Nice job! I'm also doing a DL Electronic but more a sympathetic rustoration. I can't work out if they had an Electronic sticker or not? Mine doesn't seem to have had one on but it's clearly an electronic with an untampered with transducer bracket etc.
Keep the pics coming, interesting thread. I'm currently (very slowly) restoring a battery type 1970 GP150. I bought a replacement Indian horn cast for mine but found it was about 1cm too narrow so decided to repair the original.
