...Its a 1976 Sportster Bicentennial Edition. It came from HD with the Eagle graphics and black metalflake paint.
Could this be a Scremin' Eagle predecessor?
HD made Bicentennial Edition FLH's, FX's and XL's. I have a real nice, original Bicentennial FXE. These machines came with a factory "security system" that was mounted on the license plate bracket; most people took them off right away.
I don't recall anything "custom" built on this scale between '65 and '75; although that is just my memory; there may have been something built. I do recall that HD had a very limited Confederate Edition XL in 1977.
Attached are a couple of pictures of the tank graphics.
