Serial Number question for Model 29-10

[larry earl]

I bought a Mod 29-10 a couple of months ago and there's a number etched into the yoke which i can't figure out. I see the serial # (CNMxxxx) but there's another number: 5511 just in front of where the cylinder swings out.
Anybody have a clue what this number refers to? -- Thanks for your help.

It's an assembly number to keep the parts together. It means nothing once it leaves the factory.
