Here's a mildly interesting sax: http://www.ebay.co.uk/itm/alto-saxo...t=UK_Woodwind_Instruments&hash=item3f3eba81e4
As far as I can establish this is an Edgware made B&H model from 1932 in which year B&H was formed.
Not a stencil, but an actual British horn with rolled tone holes to boot!
Could be a bit of a sleeper, as B&H horns are mostly thought of in terms of eastern European stencils.
Anyone going to have a bid? (I'm going to resist this one!)
