Correction to my earlier post
When I said the 115/119 was based on the Lark 12, it should, of course, be the other way round. I only say assembled as I doubt it would be worth having the various metal and bakelite mouldings made for two countries given the much smaller sales volumes in US and Canada, not to mention the cable hooks being not being on the "normal" side of the handle. Dont forget too there is a model 376 - a Canadian version of the 375 which was, as far as I know, never sold in the US.
But whatever! It is still a great find and definatly a keeper - now what we need is for someone to post an ad for the cleaner so we can see what the bag etc. was like. It should be possible to get you brushroll strips as well, they are probably pretty rare in Canada
