Paperweight signature help

Hello - I've recently come into a small collection of paperweights and am trying to identify some of the artists and signature. This green one has a signature and date on the bottom but I cannot make them out. Does anyone know this artist? Thank you -

 

Hola, and welcome!
There are plenty of paperweight brainiacs here, who'll be along soon, I expect.

 

Your pics too blurry to make out the name .

 

I know, but they are the best I could take. I hoped someone would recognize the signature with just the first name "John". Thanks.

 

Maybe John Burton ?
