KK336 is a Karel Knize field number for T. glaucus collected at 1500m in Arequipa, Peru. KK336 seeds available from SAB produced spiney blue perus and are occasionally available today.
This specific KK336 clone was purchased from Karel Knize and imported as a live cactus cutting into the US in 2014.
So far it looks more like a deep green TPM or Parques de Leyendas relative rather than the blue perus that were grown from the KK336 seed.
