Delta-X of Japan produced construction kits during the 1970's similar to Meccano. Of interest to us Moonbasers are there space vehicle sets. The three I am aware of are a Scramble Bug-like vehicle, a Galaxy Jeep and Galaxy Explorer.
This is the US Patent Office registration for Delta-X, a brand name of Epoch. It appears that they are no longer trading.
We could do with some better pictures of the Scramble Bug set if anyone can help out?
