Ferrari 312B3 1974: Decal "BURGO"?

Dear friends,
I need your help:

I´m looking for a high resoltion picture of a sponsor decal on the Ferrari 312B3 1974:
"BURGO" or "BORGO" ?

At the ´74 cars it was applied behind the right front Wheel

At the first races ´75 it was at the bottom in the middle of the right side pod

I have tons of pictures of this car, but not a single one which shows exactly how it looked like.
Still existing cars do not carry this sticker anymore.
And I found NOTHING at the web, even no information which kind of company this sponsor was.
Can anybody help?

Even a scan from a models decal sheet or high resoltion picture from a model would be helpful.
Thank´s a lot in advance!
