Bildico(2a) Construction Sets

This Bildico(2a) set was made in England exclusively for Marks and Spencers during the 1950s and possibly into the 1960s. It was very similar to Lynx.

Manufacturer / Distributor

Made for Marks and Spencers by Napro Products Ltd., 530-534 Kingsland Road, Dalston, Londown, E8, UK
However it is quite possible that the actual manufacturer was Lynx, as most of the parts are identical.
