I've tried to stir my father's memory and this is what I've come up with so far/ he will try to chat with some of his ex-patternmaker friends to see what they recall.
When the company was sold it was being run by Arthur Ralphs, one of the '& sons'
the business had been founded by William Ralphs, known to all as Billy.
According to my father, Billy was in his 80s when he died, we think around 1965??, having lived in Wednesfield. This would put him being born around 1885 ??
Again, according to my father, he was a patternmaker pretty much all of his life.
Hope this may be of help in some way.
Best Wishes
David
