More info just received. I showed the cannon a local member of the Company of Military Historians, who became interersted and did some searching. He found this info. I'm not going to bid on the pair, I don't like the look of them, nor do I care for the attitude of the auction house when contacted them:

Thomas Pyke of Bridgwater (1740-1829) was a colourful individual. In addition to founding cannon, he was a brazier, bell founder, iron monger, clock & dial, chandelier and spinning jenny maker. There is a fine brass two-tier chandelier by Thomas Pyke of Bridgwater dated 1789 hanging in Exeter Guildhall. A staunch non-conformist, he played a leading role in the Unitarian church in Bridgwater. He was also actively involved in civic matters and was elected Mayor on two occasions. In 1791 he opened his own bank, which closed in 1813 prior to his bankruptcy in 1815. The accompanying newspaper advert is from the Sherborne & Yeovil Mercury, dated 8th January 1781 so it is evident he was very active in founding cannon at this time.
Provenance: From a Cornish country estate, originally owned by one of their decorated Naval ancestors. Remaining in the same family to the present day.
We would like to thank Nial and Deborah Woodford for kindly supplying us with biographical information regarding Thomas Pyke.
