Made by Hedbergs Verkstäder, OSBY 1948-1958. Spelled "Mecanic" after some years, but changed back later because of legal proceedings by Meccano´s Swedish agent, who claimed that the name was too similar to their own. #1-5 were in green boxes and #1a-6a in red. The special outfits #1s, 2s, 3s and 5s were in blue. #6 and #7 came in wooden cases.
