Scott,
I'll try to get a better shot, that photo really makes it look like a sticker vs a decal. That top tube decal has always seemed weird looking compared to the other decals, almost out of place...not worn like the other decals.
I also failed to mention the dropouts are Gipiemme.
The closest I've found to my bike is at the following link

If you look closely at these photos you can almost see the outline of where a similiar top tube decal may have been on that SLE. Obviously mine does not have the head badge.
Still not entirely sure what i have.
Thanks for your interest though, it is appreciated
