Dubreq produced what would be known as a 'gold'* Stylophone. This was the 'bass' version, pitched an octive lower than the 'standard scale' models. The colour of the body is brown/tan, with a white battery/component cover.
Because of the sound quality, Dubreq would have had a hard time in selling this model compared to its' white and black counterparts.
It was a nice idea to have a stylophone covering the lower scale, but the very poor sound output meant it was not successful.
(*This model should not be confused with an actual gold--plated Stylophone that was created for a special occasion in 1973. Details on that real gold rarity can be found HERE !)
