Old School Vintage Bmx Pre 1982 Mongoose Stamped T28 Complete Bb Set Motomag

  
Used old school bmx Mongoose stamped Tange seiki bottom bracket set (28 thread) pre 1982. Removed from a 1981 mongoose.

Good condition for age, clean with good threads and clear engraving. Complete with all parts, the spacer (last pic) was chain wheel side and to my knowledge not an original part but will be included.
