Hot Rods Cadillac guru identify my rockers

Please help identify these rockers. Thanks jesse

 

Those look similar in design to the Thomas rockers I have for my olds, but they have "THOMAS" cast on them. Are they magnesium?

 

I don't know for a FACT but yes my best guess would be magnesium

 

Heres pics of my Thomas Olds rockers, as you can see they have pretty much the same features, cupped adjustment screws with lock-nuts, and separate wear pads on the tip but they have "THOMAS" cast into the rockers.

I have looked at pics of Gothas and McGurks online, they all appear different than what you have. Give you a bump, maybe someone else will be able to provide more insight.

 

Appreciate the insight. I've seen the Thomas before. Those and studebaker are all I ever come up with when searching adjustable or magnesium for the cadillac. Hopefully someone else chimes in. Maybe mine are early in the production Thomas? Before they cast their name in them? Idk

 

Im pretty sure any mag rocker will have the separate wear pad, but not all will have the cup style adjustment screw, several that I looked at used a ball adjustment screw, and some that I saw used an interference thread instead of a lock-nut.

 

Rebirth.... any new insight
