Impact Weapons have been made by numerous makers historically, many examples have no makers marks, and some do. 

I'd like to put together a timeline of makers and eventually their models, and perhaps where there is a distinct model cross over from maker to maker.

If anyone has first hand catalogues showing impacts, or impacts with logo's stamped in please send them in to davidsonleather@live.co.uk
