We had a lucky find today in an Antique shop. The Larger size needle packet holds a selection of different sized needles. The small one is the standard size and it gives you an idea of the larger one.
The packet measures 7.5 cm (3 inches ) x 5cm (2inches). We believe they date to around 1900.
Yes we do have the Treadle that goes with these. It has a very interesting Parts Tin which is like a little Metal travelling case. Will have to photograph it for you to see.
