Royal Winton - Pattern Identification Help Needed

Spent several days looking for a Royal Winton Grimwades china pattern but have not been able to identify it. Hoping you can help!

I have a small breakfast set - the tray, a two-piece toast rack, and a small open sugar bowl. Would like to know the pattern name!

Please see attached for photos of the small Royal Winton Grimwades breakfast set. It is missing two items - perhaps a creamer and a cup. Have not been able to find another small breakfast set with the exact the same pattern - or a complete five-piece breakfast set (for that matter) by Royal Winton to see what is missing. Any info would be appreciated!

The gold Royal Winton back stamp on this set, from what I have gathered, indicates that the set was made between 1935 - 1945. This particular Royal Winton porcelain mark does not have a "A" on it - having an "A" on the mark is said to indicate items made during WWII. Please let me know if this is not the case for this particular china mark.

All three pieces - the five-piece tray, the toast rack, and the small open sugar are from the same set, with the exact same porcelain mark in gold. The hand-painted kiln-cured number of 6106 (or 9019 if held the other way) is on all three pieces as well - which may have been done by the artist. It was suggested that perhaps this hand-painted number was the pattern number - but I believe that it may be an artist's identification number. Again, please let me know the scoop on hand-painted numbers on the backs of Royal Winton porcelain.

Thanks in advance for any help you can provide to identify this pretty porcelain pattern!

Good
