Skimin and Wood established in 1920 .The name is now owned by FJ Wiseman . The proof date looks like a letter S so that would be 1937/1938 which would be about right as 2" guns period was mainly the mid 30's . From past conversations with Wiseman's I don't think there are any records ,but I will be speaking to them next week so I will ask for you . As the gun is stamped " Made in England " it is fair to assume that it was made for export . They were trade makers but made a lot of pigeon guns and exported to Australia and New Zealand .
