'GIVJOY' TOYS - large fort
TRI-ANG No:6 Tower of London
ELF (Joy Toys?) 3-tier fort (second version)
A toy fort of this design (but a different paint colour scheme) was first made by Elf Crafts, in Stourport-on-Severn, England, in the 1950s. It is almost certain that this version is from the early 1960s.
