Timing Chain ID

[Joe 1320]

I picked up an ATR billet roller and the timing chain that was with it doesn't use bolts to hold the sprocket to the cam. It uses a key on the camshaft snout. Anyone know who's chain this is?

You'll have to cut and paste the link of the pic.....

So noboady has seen this before? Suppose it is most likely a custom ATR chain?

Don't know what brand it is, but it looks to be a timing chain for the pre-78 oddfire Buick V6s and the old smallblock Buick V8s...
