Rounding up ....

I believe the Silent Q belongs to Rob (Turbopower1984 I think) who posted pictures of a purchase he made before Christmas.
Although superficially the nozzle may appear to be similar to the National it is quite different in that the connection swivels from side to side in the comventional manner, whilst that of the National swivels up and down - as I said earlier this was a common arrangement in Europe, not in the UK.
We discussed (privatly)a few years ago about President models being manufacutured by Bylock which I think they were, what I did not know at that time was that they were, initially at least, based on Apex designs. Bylock only started manufacturing vacuum cleaners after WW2 (previously they manufactured hair dryers) the Silent Q predates the Bylocks by at least 10 years, and even that had been around in various forms for about 10 years or so before that. It is co-incidental that Vactric sold a couple of Apex models (design at least and possibly manufactured in US as well) as their TOL models - the Apex with the swivel pivot at the end of the handle - Jack has footage of using one of these when he attended the convention in North Canton in 2008. I am not aware of any other connection between Bylock and Vactric apart from this co-incidence, and these models were not (apparently) sold after WW2 in the UK.
Rick, again I am not aware of any connection between Vactric and Electrolux, indeed if anything it has a closer resemblence to Goblin models than anything else - although of course these both would have been influenced by the Lux designs - where Lux cannisters were almost marketed as heavily as Hoover uprights. It was not long after Hoover produced their Junior 370 that both Vactric and Goblin brought out similar concept machines. The Vactric model hardly changed through its 22 odd years of production, the Goblin evolved rather like the Junior did - I am firmly of the belief that once Hoover brought out a new model Goblin took it apart to produce a new model as close as they could without infringing Hoovers patents.
The hose attachments for the Bylocks, particularly the early ones are quite different from those of the Vactric - for example Bylock couplings were always plastic whilst Vactric were metal.
Stephen, the wooden handled machine could be a Premier, indeed it could even be yours as the picture was taken at the get together in 2007 which you attended.
