Belleek Irish Leprechaun on Toadstool Pariah Porcelain Figurine 6th Mark Vintage

This piece has letters stamped along the base. I can make out "Good Luck" on the front and "Irish Leprechaun" on the back. I can't make out the text on the right side of the base, but I think it is "sonas ont" which I believe is referring to the luck of the Irish (the luck and 3 wishes you get if you catch your Leprechaun!)
