Campy Record Chainring Orientation
I have what might seem like a crazy question. My Campagnolo inner Chainring has name and 42T stamped on same side as what appear to be Chainring backing nut recesses. It seems like you'd want lettering to face out like outer ring but doing that puts the recesses against the spider. It just looks strange having lettering facing the frame. Any thoughts?

It is probably just easier to stamp them on the same side as the recess as they move through the milling machines
but be prepared for a 29 paragraph explanation of how they are machined and stamped.

I kind of figured it due to uniform processing. It just always bothered me. It just came up again today because I disassembled and cleaned the rings. I also took the cogs off of my Regina freewheel to put a 26T large cog on it for a little lower gearing. I'm going back to N.Y. for the 5 Borough Tour in May.

I think 144 would have been Record in 1984 ?
I thought the same thing, but 53 has pin for chain drop and 42 doesn't. Machining process seems to make the most sense. It has been working fine for 38 years; it's just always just not looked right during all of that time.

Better question is at what size did Campagnolo stamp the full brand name on the counterbored face?
I recall my 47t rings from long ago presenting the full name outwards. Not sure on the 45 or 46.

They are stamped on both sides. I have examples of both.

I hadn't noticed it. But, I did have some tooth wear on the inner ring after decades of hard use. It would be a benefit to rotate the inner ring from time to time to prevent all of the ring wear to be in one spot, and even flip the ring to wear both sides of the teeth.

Chain ring
Sounds like there milling and stamping machines processed all the chainring ( inner/outer) on the same side. They didn’t flip the inner ring just to stamp the tooth size and campagnolo cause that would mean and extra step in the process. Or could of been an engineer just jacking with everybody.

The extra webbing of the outer Nuovo Record chainring obscured the portion of the inner ring where the tooth count would normally be stamped, therefore, the stampings were put on the opposing side, able to be read easily from the non-driveside. When Super Record rings did away with the extra webbing, the inner rings could then be stamped in the same way as the outer ring. This photo should serve to explain my thinking:
