Ruger cylinder??

[xtratoy]

Has anyone ever seen a Ruger 22 Mag cylinder marked like this one? http://www.ebay.com/itm/Ruger-22-Magnum-Single-Six-cylinder-655-/181857122274?hash=item2a578777e2 I'm not an expert by any means but think this may be wrongly described or misidentified.

It's a Colt cylinder.

I think Cholo hit the nail on the head looks like a Colt cylinder to me
