I met Harry Toye in the early '60s when I was in my teens. Grew up in Sarnia, know Corunna. Did you know Sherm and Ken Ball who operated Corunna Hardware? Ken had gone to Colorado to take the gunsmithing program, and ran quite a gun counter in the hardware store. Sherm was ex-RCMP.
In my tickle trunk I have a new in the grease BSA No. 4 replacement barrel; just the thing for such a project...
