Friars Egg Holder. Vintage

Hi
ere before on the net
I have researched these lovely little Friars that get bald heads once the eggs go in.LOL. However, mine is very similar so those of a maker called Weiss. However mine have the brown coulour inside when many dont and seems to have a makers initial and name inside. I have tried blowing the picture up but still cant be sure. It it may F. something. If anybody has better eyes sight than me can you tell me what you think? I know I have seen these somewhere on the net but today I am not having much luck.

Thanks

Elaine.
