Lectron Replacement parts

Braun Lectron https://de.wikipedia.org/wiki/Lectron, in USA: Raytheon Lectron https://en.wikipedia.org/wiki/Raytheon_Lectron, was an educational electronic kit in the 60s/70s. Each 27x27mm box contained one or more electronic components (transistors, resistors, capacitors etc.) with magnetic side/bottom contacts which could be simply put together to form a working electronic circuit. Unfortunately, the kits are no longer produced, and can now found at internet auction sites.

The models here are very close replacements to the original boxes, and with some available components (special magnets and metallic contacts) they fit nicely in the original kit, to replace lost parts or extend the kits with new components.
