Headlight

Past weekend we had a barbecue with all the guys of the evening school I'm going to.
Tim, who organized it, had a little present for me. He gave me this nice old headlight that used to belong to his girl's grandpa.
They didn't know what it's from but on the top it says 'BW'.
At first I was thinking it would look nice on an old fat bobber style project, but since it's pretty big,  now for some reason I start to see an oil-tank in it.. Don't really now yet, but it's so cool!

(sorry for the crappy quality 'phone photo's' but I forgot that I had the quality set to the minimun, stupid me!!)
