vintage bayko building outfit no 13

Probably the greatest toy ever made ( before the health and safety boys got their hands on it).
This is a vintage set of Bayko construction toy, set no 13.
I'm not sure if its complete but it has a lot of pieces including the base, roof, windows, bricks and the steel rods as well as the instruction booklet.
The contents are in very good condition but the box is a bit worn.
Box dimensions: 16 x 10"
