Western Aviator deck

[Chuqii]

Here is an interesting find.  I'd always seen the SPCC Aviator decks, but I'd never seen one from Western.  Based on the tax stamp (10 cents, 1924-1929), I'd guess this deck came out about the same time as the SPCC deck, so maybe SPCC put the kibosh on this deck.  Anyone know any details about these Aviators?  Which were first?

Just checked my Hochman, and it has SPCC Aviator c1930.  WWPCM has SPCC Aviator since 1927.  Best guess for the tax stamp on the tuck is 28, though could be 25.

First time I've seen the Western.  Very plain, but satisfying Ace.  I don't mind the backs either.
