Featured Botany experts! What type of flower?

I thought a poppy but our UK ones have black centres?
Or has artistic interpretation exceeded botanical knowledge here?
It’s an ‘Original by Robert’ huge enamel brooch.
Thanks for any suggestions

 

These were big 1967/68 & did not pretend to botanical accuracy.

 

Sorta a poppy but as above.

Debora

 

Hmmm, wonder if it's based on this Robert of similar color.

In the late 19th and early 20th centuries, it was expensive to provide each medical school student with a microscope, but anatomical details of plants can be tough to see with the naked eye. Medical schools and museums (including the Smithsonian) relied instead on botanical models like these for student instruction. Manufactured through the 1920s by the Brendel Company, a German firm founded by Robert Brendel in 1866, these botanical models are made of papier mache, wood, plaster, gelatin, and other materials. Many can be “dissected” or disassembled to show the internal anatomy of flowers, fruits, and other organs. Flowers represented in this set include cacoa, henbane, iris, monkshood, poppy, and rose.

 

It's a poppy. Papaver rhoeas.

 

This is now irrelevant as apparently you can’t list British Legion Poppy brooches on eBay .
Who knew?
Not that this is a British Legion one, never has been and wasn’t trying to list it as one but it seems all types are blocked. New ones seem to get through it’s just the used ones blocked as apparently they should only be bought from BL.
Ridiculous.
