Unknown Greek coin (Galloping Horse)

Hey guys, 

Back with another worn ancient I can't ID. 

Greek coin i believe, with a horse motif and some lettering, similar to a chalk on of Euthydemos but lettering does not match. Help would be appreciated.

19mm Diameter, ~4 grams (+)

Ok, I found somethings that may be close to it:

N#170431 - no lettering

N#46899 - closest I could find so far
