That doesn't look like the Diode listed in the srt pages at the Rokker something? My brain damage just kick in big time can't remember the name of the site now but they have the mod to silver oxide and it lists 1n7511 Schokkty Diode? Maybe what you have does something differently? What do I know? I get to know IF your pieces would work to lower voltage from 1.55 to 1.35 I'm all eyes!! :-) Interested that is Kind sir!
Have a good one,
