Price guide only shows two EIN's for a McLaughlin (front skirt) No, 16 (rear skirt) with a letter 'R' in the wire groove. The one I have is obviously doesn't have an 'R' as in Roger. This one has what looks to my not the greatest eyes to be a #5. It's a wonderful think for me that my camera at least takes wonderful close-up pics for me even if it does a lousy job with the color frequently. Anyway if appears I have an unlisted insulator here. Anyone have one likie it? Has RDP's and no numbers on the front skirt which eliminates the 010 ein automatically. The remaining EIN's have no #'s inside wire groove. Maybe it is a 020 but nobody noted the #5 inside the wire groove. After all, who would think of looking for any embossing located there. What do you think? Would love to hear from you McLaughlin collectors of wisdom. Thanks.
