Lee Valley Tools operate in Ottawa, Ontario, but they cannot send one of these to Quebec,(next door Province).

'improvements patented in Europe Dec 1885'. in France perhaps? Hence the strange Quebecois position.

..what's the possibility that this device has it's origins in (literally) a masonic secret..?

..it's one thing for a mediaeval mind to design a rose window, it must have been quite another to ensure that all the other parties involved had clear sets of identical drawings to sign-off, archive, & work from..

..much scope for musing & mental excercise when one thinks seriously about the logistics and organisation involved in building one..

I expect a Canadian will explain better but my understanding is Quebec Province law differs enough in several ways to put companies outside the province off from selling to them. Requirements like a potential need to label in French, different Customer Protection rules, and a Code rather than Common Law system. Bit risky to deal with if anything goes wrong and enough bother and cost to justify sellers choosing to walk away. Borders inhibit trade.

Edit: __ His use of a ‘polygonal disk’ looks like a devious [and presumably successful] avoidance of the earlier patent !!
