Stringed puppets, SL thought to refer to Stringed Luxury puppets
This is the puppet normally with the molded head.
At first it was only used for character puppets such as TV stars, Cinderella and the Alice in Wonderland series but later many other characters were made.
Strung on a "standard control".
The largest range of characters are of this type including the 1963 range and these are listed seperately
The company also placed Clever Willie into the SL range even though he had a turned wooden head but only because of his price which was the same as the normal SL Range. Rupert the Bear was placed in the SS range yet is a SL puppet, again due to being the same price as the standard SS range.
