doublegunshop.com - home Forums Thread Like Summary - British Patent information sources

I have been buying examples of odd fastening systems used on doubles like under lever, side lever both right an left side, forward and rear wards facing side levers, thumb openers both under and tang types. I am interested in researching the original British patents for these. Is there one or more sources of information for them? Figure it would be nice to have the patent information for them to pass on to the next owner. Heck I just like reading about this kind of stuff.

My current favorite is a 20 bore Pape thumb under lever hammer gun. One sweet gun, which is a pleasure to shoot. 30" nitro proofed Mod and Full barrels. Also a neat Joseph Smith forward facing bar in wood 12 bore hammer gun. Missed high eight with it last weekend for a 25 straight. I understand why that design failed.

The Crudgington Baker 3 book series is a great place to start:
