Brandon eyepieces in the late 1960's continued to improve. By Sept 1968 they were advertised as being parafocalized, and threaded to accept "Vernonscope Filters". (In the examples I own of the prior series Brandon oculars had NO provisions for filters at all due to lack of threads on the bottom of the eyepiece barrel.)They also were individually cased in a black vinyl pouch with belt loop. It should be noted that to this day Brandon threading is unique to Vernonscope filters only!
Between 1977 and 1979 Meade had introduced a "Series 2" Orthoscopic line of eyepieces available in both the 1.25 inch barrel size or the Japanese standard barrel 0.965 inches. The "Research Grade" line of both Erfles and Orthoscopic are of course retained and were successful for many more years before production ended. Both the Series 2 Orthoscopic eyepieces and Research Grade are all described as multi-coated and parafocalized. Note that several 2 inch eyepieces are also advertised - a 60 mm Kellner and a 32mm Erfle . (They are not described under a Research or Series 2 ocular.) This is per S & T - Sept 1979.
Dakin Barlows also highly recommended are another Venonscope product. Click on above image for various sizes. Originally developed by Ralph Dakin.
