My Dad gave me my Golden 39A for Christmas in 1975. (No it's not for sale.)
In addition to the gold trigger, it has white line spacers at the butt plate and pistol grip cap, also the front sight hood. Another "feature" is the odd little black-and-white "bullseye" plug made of plastic, inletted into the toe of the stock. I recall Marlin made much of the trademark "bullseye" at the time.
Well, the seventies weren't the golden age of taste and style...
