Vintage Canadian pacific ry Co Glass insulator 1885

THIN PRINT CANADIAN PACIFIC RY There are two moulds , a square dome and a round dome. I believe that when the Raised Band 090 Canadian Pacific Ry moulds were finished in 1884 the No Embossing Montreal style moulds were reworked to become these Thin Print Canadian Pacific's to replace them. They seem to be a short lived production . There was a fire at North American Glass Co in 1885 which burned almost all of the factory . These moulds may well have been lost at that time. This would have led to this transfer by Canadian Pacific to Hamilton Glass Co. By about 1885 the Hamilton Glass Co had just bought the Burlington Glass Co and were on the rise. The Thin Skirt Canadian Pacific were produced there about 1885 showing that the Canadian Pacific had placed their order with Hamilton . Because the embossing on these Thin Print insulators was so fine and was never re-engraved we can see there was not a large production of these. One thing to note is the colours of these are the same as the Whittle Mould Un-embossed insulators showing that when the No Embossing Montreal style were done the Whittle Mould replaced them as the no-embossing mould. it is chipped when I got it. see pictures.
