Thanks Jani for the effort. I think his business model closely resembled that of Gustav Tichy and yes production may have been a dozen sporting weapons a year. I'm not sure on the British sourced tubes but it may be a British steel type like JNO HY. ANDREW & CO. LTD TOLEDO STEEL. Any idea what happened in Opawa at the onset of WWII?

Kind Regards,
