Interesting to see your mechanical sewing machine, I have one exactly the same, you may not realise it but yours is probably one of the many made in Clydebank just outside of Glasgow. The singer factory in Clydebank was the first Singer factory outside of the US, it was opened in 1884 and by 1913 was making 1.3 million machines per year. At its peak it employed 15,000 people and had its own railway station which is still open today. Along with the rest of UK manufacturing output dwindled from the 60's peak and the factory closed in 1980 with the final loss of 1200 jobs.
The machine I have dates from just after the first world war and works as well as it did when new.
Good idea for a thread
