As we know, Simpsons moved out of London when their Clapham factory was bombed during the blitz in 1941. Convention has it that prior to the blitz, all Simpson brushes were labelled "Made in London".
Here is a quote from Gary Young, great-nephew of Alexander Simpson, the original founder of Simpsons, asserting the conventionally-assumed truth:
"Afraid it is not a London made Simpson. If it was the decal would read 'Made in London' - this was changed to 'Made in England' after the move to Somerset."
So why do I mention this? Because I found an April 2, 1938 copy of
The Hongkong Telegraph (and another from December 8, 1937) advertising Simpson brushes, depicting a brush with a decal saying "Made in England", i.e.
before 1941.
So, if the decal says "Made in England", it can't be said that the brush
must be post-London (post-1941) production. The evidence above is clear.
If the decal says "Made in London", then yes, it
must be pre-1941, because that was where the brush was made.
One conclusion that can be drawn is that Simpsons, prior to 1941, were already beginning to expand globally, and labelling a brush "Made in England" carried more of an international appeal.
Coincidentally,
The Hongkong Telegraph continued to advertise Simpson brushes until early 1941, just prior to the Japanese takeover. Bit of a double whammy for Simpson, I'd have thought.
No offence to anyone, least of all Simpsons, but verified documents beat memories. And it's important, at least in my view, to continue to review and sift through the facts as they come to light. An
argumentum ad verecundiam just doesn't cut it.
