Yes the upper foot peg was added on . The blue on the seat pivot looks original , if so , it is a Big Blue . Bird used this same frame for both models of Golden Pinto , Big Blue and War Eagle and probably others . Sold by Sears Roebuck , JC Penney and Bird Mfg. The center stand means it most likely is 1974-76 . They are nice riding and a 5 hp Briggs works great in that frame if you do not use the original 4 hp Tecumseh . Good Luck with the build . Need to see your forks to know more about it .
