The tag says it all. You have a U.S. Philco Model 91, Code 123. The B stands for Baby Grand. See Ron's site here for cabinet designations: http://philcoradio.com/tech/letters.htm By the way, if you had a Model 91A, it would say A on the tag and it would also be a Canadian version and would also indicate this as well. Basically the power transformer is different, due to power differences back then in Canada. 25Hz instead of 60Hz mainly.
