Well, by all indications, this is a 1935 Lone Eagle with a copper colored dial. Engraving goes to the end of the lugs and has the telltale "x" in the center at 3 and 9 positions. Face has gold numerals and black seconds tracks. Watch was represented as estate fresh and the crud on it (face/case/band) says it's true. After handling this and taking it apart and cleaning it under magnification. whatever this is, I believe it's legit with the possible exception of the hands (if it's an LE) and band. Band is a Fitman & Keller and wear matches watch casing.
Caseback is marked with serial number, "10K Gold Filled' and "Bulova" with an American Standard shield on the edge near the nib for opening caseback.
This is the oldest Bulova watch I have ever encountered with a copper dial; and it's in a yellow gold hinged case. Plastic crystal is a little hacked up, I'll be polishing it shortly. This just came in the mail. I let it warm up, spun the crown once and it started running. 2 hrs in and it's keeping time.....$16.50....nobody was watching.
