id signature on pottery vase

Hi, i was wondering if anyone could help me identify the signature on this pottery vase. Thank you for any information.

 

THAT is another tough one.....that I can't really read..... @anundverkaufen is awfully good at deciphering......maybe he'll pop in since I just tagged him....I also tried to enhance the siggy......just not sure if the first letter is an 'O' or an 'A', and if it's two names or one......

 

Yeah unfortunately the signature is tough. The base of it us actually round at the bottom and almost comes to a point which I thought was unusual. I thought "a" as well or "c"

 

Sorry, I looked, I tried, no luck.
Looks so very familiar, I think I have a piece with the same signature.

 

Could it say something like Cambodia?

 

Thanks for the info guys. Anundverkaufen if you come across the one you have let me know! Say_it_slowly I tried googling but didn't come across any matches. It's a tough siggy to read unfortunately.
