Unidentified Characters

[brholcomb]

probably not your typical request! I am trying to solve a very difficult puzzle involving different character sets and ciphers. I'm making good headway but I am stumped on a certain group of 4 characters (image attached). I need to convert them to english characters and the closest fit I have found (but no cigar) is Northern Iberian. I would very much appreciate if you would take a look at the image to see if you can successfully identify the language/alphabet.

 

Thanks!
