does anyone know when dufferin made cues with a brass uni loc. just found one thats been sitting in a closet for about ten years, didnt know i had it, i think i got it on a trade. anyway, put a shaft on it and it hits unusually well. was it madfe in china or before it was sold to the chinese? i kinda wanna get it re wrapped and put a decent shaft on it, but i also dont wanna put lip stick on a pig. in case i might wanna sell one day id like to at least make my money back. its a long shot bc theyre chepo cues, but if anyone would know it would be here. thanks in advance.
