Looks identical to the BMX Magnums that Tensor in Darlington were churning out around '82-83. I remember my sister getting a metallic red one BITD, it was an identical f&f to that with a 2 piece crank with a cotter pin on one arm, also had a 'Made in West Germany' decal on the seat tube, probably all from the same generic manufacturer.
