OK, as mentioned in the previous post, I did go looking for my magnifying glass and found that two of the bobbins were dated 1814 and 1823 and all except two had similar markings on them.
here's the detail on two of them, please excuse my sketches
My small Book on bobbins describes Honiton lace bobbins as having anchors, ships, fish, diamonds and hearts as decoration. Honiton lace was made in East Devon before being badly hit by a machine lace factory being established at Tiverton. Before 1816 there were 2400 lace makers with the number dropping to around 300 by 1822. The description matches the markings on my bobbins.
