Series one Frijole and quite a find, they were sold in kit form so few are perfect and being so small the original builder likely bent the bars and the gusset just makes good sense but I do not believe they were intended to have one. Pegs were added as well but it does not hurt the value IMO. If the price is right you should buy.:thumbsup:
I forgot the fenders, and a better pic would tell how well it was really done. Something about it looks wrong on the rear downtube but it may be the picture. ST you got the ID, especially showing the kit form pictured as one would be purchased. I'd love to find a good to awesome example in either a series one or two but have nearly given up, still I will keep an eye out.
