Hello Dognose, another bus has finally come. I’ve actually been waiting for it for over 3 years. I recorded a photo of these unidentified spoon marks below from the inter net in May 2014.
I thought it likely to be Canadian Provincial but on first researching I turned up no maker for the spoon. Two nights ago I reviewed my “colonial photo file” and wondered if I had got any better at researching. I had. This time I quickly found “J.G.J” listed in 925-1000’s American makers as “Joseph G Jodah” of Toronto and thus to this post.
These marks are a bit different from your photos so could they be a little earlier? Could they belong to someone else? I note also in the forum topic viewtopic.php?t=31885#p79947
you indicate your silversmith was also known as “Jodah George Joseph. I did also find a reference to a “J.G.Joseph & Co” with an un-illustrated mark of “J.G.J & Co” in a rectangle. Surprisingly this silversmith’s active dates were given as circa 1850-1870 and was said to be working in Toronto. I also found 2 Canadian references describing items made by “J.G.Joseph & Co” including a coffeepot and a ceremonial mace but with proposed dates for manufacture of 1860 despite the 1857 death of “J. G. Joseph”.
