Rollmaster billet timing chain
I think this is an older Rollmaster billet seamless double roller timing chain that came with the Rolon blue chain. Later Rollmasters came with an IWIS chain. Has 9 way lower sprocket. Chain is tight when installed, maybe 1/4" deflection. Lower sprocket has some PO's installation marks on it and a few burrs on the keyways but a file would clean them up. cam sprocket looks great, lower sprocket I think is heat treated and nitrided so it looks darker. I went to a gear drive and a silent chain with a tensioner on my other builds.
