Poter 1986 Musical Clown Doll/Toy

• Musical wind-up clown doll(?)
• Head moves in a circular motion back and forward to a happy tune (not a "Small World"). 
• Small crack on his styroform bottom.
• Fabric fully intact.
• Original thread attaching card - threadbare.

Research done:

• Found many Poter clowns online but have not seen this particular one before (purple hearts and simple line mouth)
• Other Poter clowns have plastic wind up key - this has a metal one.
• Other Poter clowns have a Sankyo musical device in them for the tune.

Any help appreciated.
