Short model tin Parker case with rose velvet lining. (Parker made primarily two cases during the period a 6″ case and a 4-1/2″ case for collapsibles, most have unreadable marks and many are not marked- especially the shorter version as seen here) Tin is sound with a few surface rust spots and dents here and there from typical use. This type of collapsible earpiece spectacles date to the 18th century and were very popular for field use as they were more easily carried, had loops for a retaining lanyard and more easily replaced as being adjustable, one did not have to have the frames especially fitted. Gold metal frame with rounded rectangular lens. One earpiece is stamped with number “11”. Not bent up or twisted as is so often found – the extensions slide firmly and stay in place. One of the loops on the end is worn through but still all there. I have seen this common issue easily repaired with some wire wrapping – could easily do it if need be. Will display very well. A good solid respected and used pair of specs with a good tin case – made for the field and traveler in mind.
