The rockers have a "308" stamped on one side and the other side has a W followed by a number I saw W12 W7 W24 and a few others. Any idea which they are?

just looked at my stockpile of rockers...

I have a set of 273 mechanical rockers that have 308 stamped on them...so I would say they are 273 rockers.
