I know that Gary Little John frames were the first rigid frames created, but can someone please tell me did the 1976 frames only have single gusset like the Redline 76 model? Were the 1977 Glj different? I cannot find no pics of any 1977 Glj frames at all? Also i would like to ask, did Skip Hess copy the first Mongoose Bmx frames from Gary Little John? My friend from the U.S.A told me this years ago. Any info would be greatly appreciated.
