I have these diodes that I bought from small bear in 2011 and have been in my diode drawer for over 10 years. They lost their label and I don't know which diodes they are. I was able to dig up the email receipt and it just says "NOS germanium diodes"

Anyone have any idea what they are?

I don't know the answer but the two stripes and inconsistent thickness of the first band look a lot like these Bulgarian SFDxxx diodes.

Maybe you can find an SFDxxx part number with the black and red stripe (I didn't look that far).

The black first band means they probably aren't one of the common Russian diodes.

I've found you can't color code diodes like you can resistors. Sometimes you can. I'd say they are 1N34 clones.

I did. They just said that order predates their current records
