You misunderstand. Not a conversion cylinder. Just putting a blackhawk cylinder in there. Basically it's the same gun. There is no ejector rod or loading gate, so you'd have to pull the cylinder to load and unload.

Since this would NOT be a conversion cylinder, there would be no backplate with firing pins. Would, most likely, have to reshape the hammer nose. Couldn't just stick in an OM Blackhawk hammer, as they used a flat hammer with a separate firing pin.

I'm not talking about a Colt Army revolver, I'm talking about a Ruger Old Army.
