"Does anyone here have a picture of a "real" 1n34a Ge diode?
If you go to eBay you see probably 10 different diodes. The ones I have show distinctive double black bands, some clear glass showing, and are about twice the size of an 1n914."
You would probably need 10 ten photos to show all the different "real" ones.
As Induction said, the small ones are almost certainly Si Schotky work-alikes, while the larger ones should be Ge. Be aware though that they can have one wide black band, two narrow black bands, or even one wide green band. There may be other variants too.
There are other diodes too that have one or two black bands - old 1N60P spring to mind, so effectively look identical to the 1N34A you are describing.
This guy is having the same issue:

We have just found out that Russian D9 diodes also come in silver cases as well as the more common clear glass - something I don't think anyone here had come across before. See the "mystery parts" thread further down the page.
What I'm trying to say is that I don't think anyone can say "these are the real deal" or "these are wrong-uns" just by looking at a photo on a website, or an ebay or amazon listing.
And whether you even get the same thing as in the photo is another matter altogether...
