I think that is a first-run Spoiler, circa 1982. IIRC, these were the only decal-ed Alembics ever, the decal was very soon abandoned in favor of a brass logo. FWIW, I like the detail within the decal logo, but must confess to favoring the brass over it... it just seems more... Alembic. I assume that was the consensus back then too, since they didn't last long.
*There was a rash of fake Alembics a while back with decals, but this one is legit.
