If the transformers are all from the right period, it's a good guess that the amp in question is the real deal.
On the ebay Super Reverb posting the OP listed, that grill cloth could very well be nicotine stained from the original - I've seen a lot that were that dark before washing.

You're gonna find plenty Silver Face Amps that say they were Black Faced. Do transformers, speaker codes and serial # all fit the right timeline?
That's not as big of a deal as an amp with irreversible mods like extra holes drilled, extra switches, Bootleg Control Panels, Wrong Tolex, Incorrect Replacement Grill Cloth, missing serial numbers and back plates. Usually someone selling a clean vintage amp will already have most details posted.
The brown wheat grille was the first thing I noticed out of place. The tube complement decal on the back does indeed have a stamp code attesting that it is Blackface era, but the decal does not have any paper curling or browning suggestive of an amp almost 50 years old.
