Wanted: 18t 1/8 EAI or similar cog + decent lockring

I have an 18t 1/8" cog I boght at Condor before I knew jack shit about what I was doing. (What I was doing was running a 3/32" chaniset.)

I still clearly know jack shit because I have no idea if is an EAI cog (it came in a baggie with a handwritten label, no other markings) but if it can be identified as such you're welcome to it - it's currently being used as a paperweight.

it will say EAI or euro asia imports on it. if it's a cheap one from condor with no writing on it's no good for me as that's what i replaced as it's chainline was closer to the hub flange.
