in view of the size Keith, I'd suggest this is Nazeing shape code 88/1 - and pink does seem to vary considerably, from pale to quite intense.
In Geoff. Timberlake's book, he shows working drawings (black and white hand drawn as opposed to coloured pix) - of which this pattern is one.
He comments that "these working drawings were in use until the end of Art Glass production in the 1950's. They show shapes that varied from the range shown in the 1930 catalogue".
This may indicate that your bowl is post rather that pre, war...............I stand to be corrected, but it does look that way.
