Forrest — I've checked Reynolds, so it's probably not Walsh, although Walsh used a 16-point daisy in a square panel motif, similar to these rosettes, in their 1930s pattern
Sandown. These motifs, restricted by the square boundary, required highly skilled cutting or copper wheel engraving, so in the Walsh case it was only carried out by their top man, Mr. Douglas.
I've also checked Benson & Hayhurst, but with no luck.
The shape looks postwar to me.
