I just revisited the eBay listing and have noticed the low serial number and lack of lettering on the body parts. This is an earlier Standard Speaker that has been modified. I see also that the lister has been alerted and edited the listing. So, it is rare but incomplete. I don't know where a collector would find the correct dual stylus bar, glass diaphragm, and crosshead to complete the unit. Any suggestions are welcome since one of my Standard Speakers is missing the same parts? Best Wishes to All, Al Who needs a magnifier to see many eBay photos...
