Goblin M4 and M8 Clock Movements
In 1973, Goblin models were being made with both M4 and M8 clocks. They can be easily recognised by their beige thumbwheels.
The M4 was used in the 855c and 855d. The M8 was used in the 853a, 854a, 855a, 854b and 855b.
By August 1974 production of the latest M8-C model was in progress, but the M4 movements were still being turned out at a rate of 4000 per week.
Goblin's management agreed to slow production to 1000 a week over the final few months of 1974, transferring workers to other products as required. They would stop making the M4 clock altogether at the end of 1974.
