Sorry to bump such an old thread, but thought anyone researching Tranters might be interested in the following:
This gun has nothing to do with the John Hayton family as far as ownership goes. John Hayton was a well known Eastern Cape Gunsmith and dealer in the mid 1800's in Grahamstown. As was commonly done in those days, a dealer/importer had his name put on the guns he retailed when he imported them from the manufacturer. There are many Tranters here in South Africa with his name on them, along with other firearms. It merely signifies it was imported and sold through his dealership.
