If we’re talking about the same guy, it wasn’t a Coker. JJuggle went to meet him when he got to New York, he should be able to give you more info about the guy.
EDIT: Found the thread.
Surely you remember this?
And this?
This thread carries links to both the Schlumpf option and the Dave Stockton produced version of Pete Perron’s geared Coker.
Some more reviews of the Schlumpf here.
