my guess is schon made that cue as part of special line that some reseller carried special for them.. like the cue stix schons are all CX models and the Omega Billiards are all schon OM's.. you best bet would be to email evan clarke and ask him.. he will be able to tell you.. but be forewarned.. he will only answer specific questions you ask.. so make sure you ask him exactly what you want to know...
