Polish cap badges - makers?

[DougSA]

I would be grateful for any insights on the makers of the attached cap badges. I am assuming that the one on the right is likely made by Spink of London. They are actually slightly different in size, the one on the left being 50mm from top to bottom and the one on the right slightly larger at 54mm. The photo is deceptive due to the raised angle of the one on the left, due to the screw fixing on rear (rather than blades).


Any insights appreciated!
