Most of the Canadian Victrolas differ from the American version only in details if at all. That said, in the open horn era, Berliner offered it's own line of models which differed significantly from the Victor machines. I
think after about 1906 one could get BOTH lines from the local dealer...the ads spoke of " "Berliner
or Victor" machines and towards 1909 Berliner began to phase out their own models and replaced them entirely with Victor I through VI as well as the Victrola line. The Berliner open horn machines used both the Berliner reproducers and the Exhibition sound box. However the tapered tone arms on the larger Berliners: the Model J and GT for example
look the same as the Victor arms but I understand they are not interchangeable.
By 1912 the Berliner machine catalogue was offering American models only.
After this point there were from time to time different models offered up here ...like the Victrola XIII of 1920...and then others in the Orthophonic era. I have the 1927 and 1928 machine catalogues...from which I scanned the Alva blurb....and we did not have the full line of American instruments ,but we did have a couple which weren't offered in the US...the Alvara being a case in point. And there are odd little things, like the children's Victrola, the 1-2 with the coloured decorations which up here was the HMV model as sold in the UK, if the illustrations are to be believed.
It's all rather complex but lots of fun and I have always been meaning to write a full article on this subject but I never have the time to research the
Canadian Music and Trades Journal which would requite a trip down to Ottawa to the National Library. I should go before the wretched Tories sell the whole collection for recycling Oops? Did I say that out loud?
