this would be well post-archer logo, when they had the round sticker with the "wave" in it.
On that specific final year, WAS IT GALVANIZED UNDER FINISH?
at that point WHAT WAS THE TOP FINISH? PAINT? THAT THICK QUASI-PLASTIC STUFF?
again, at that point in time, DID THEY HAVE AN INTERIOR COATING? LINER?
Thanks in advance, Fred
