1930's - 1950's Bayko Building Set

1930's - 1950's Bayko Building Set 
Bayko was a British building model construction toy invented by Charles Plimpton, an early plastics engineer and entrepreneur in Liverpool. First marketed in Britain it was soon exported throughout the British Commonwealth and became a worldwide brand between 1934 and 1967. The name derived from Bakelite, one of the world's first commercial plastics that was originally used to manufacture many of the parts. Bayko was one of the world's earliest plastic toys to be marketed.
 
The selection and colours in this set suggest it is pre-war Bayko, but there are some ornamental elements included that were from later sets (This is a guess).
 
The set is in pre-loved condition with ageing and some discolouration but there are enough parts to make the models in the guide.
 
The wooden case is in good condition but some ageing. Not sure if the case is original Bayko or made\aquired by its first owner as a way to keep all the parts together and sorted. It certainly fits the part
