I always thought Callum split & Norman was formed from the split around 1967 ish
Looks like Callumcraft continued later than I thought unless it was just the sale of stock hulls (Unlikely but - NMP - North Manchester Plastics ie Norman !) My Norman is 1968......
From History I always thought that the Callumcraft was the forerunner.....
