Help identifying vase makers mark? Arts and Crafts? European?

I have had this vase for many years.   It is not in the best shape but I’ve always liked the look of it anyway .  It has a very clear mark (looks like a clover leaf) but I have not been able to identify it .  It came from an estate where most of the items were from the arts and crafts period,  So I always assumed it’s about 100 years old.   It kind of has a hammered look to it but I don’t know for sure that it’s arts and crafts though. It has been suggested to me that the presence of a number on the bottom may indicate it is European. Any help on the manufacture would be appreciated. Thanks.

It certainly looks Art Deco period. Not a mark I recognise. Maybe one of the US Art potteries?

Thanks for the reply. Funny the American pottery people I have spoken to say they don’t recognize it either and figure it might be European. I’m guessing it must not have been a very prolific manufacturer. May have just been disposable stuff for it’s day and not collected or known these days.
