Since there are examples with Canon Fanget on the tubes and an encircled M&P in the same location, which I assume is Merley & Pouly (canonnier repreneur de Fanget-successsor of Fanget???), makes one wonder if the encircled F&Cie(Companie) is Fanget & Companie? Is there another Canonnier F. that would be in the running? I wonder if Fanget and Marsot ever joined forces?
Interesting in the blog that they attribute Ronchard Cizeron as importing the fluid steel tube making machinery from Liege.
Kind Regards,
