C3 Power Brake Booster

[Sheldon S.]

Could someone tell me how to decode the date code and model number on a power brake booster, this is from a 1971 car. Here is what I found stamped on the circumferance of it, 1 112 B 9092.
Thanks in advance
Sheldon

Sheldon,

I have a 71 as well. I've only had it for 4 months. I've been collecting the numbers and documenting everything nicely. I didn't realize there were so many numbers but I'm having a blast since my car is mostly original.

Where is this number located on the booster? This will give me something to look forward to when I finish work today!

Thanks,
Greg

Greg,

On my booster it is stamped into the outer half(the side that the master cylinder bolts to) close to where both halves join. It is close to the top if mounted in car but this might not be the same on all. Was hard to see at first, as I have had it off my car for a few years and never noticed it until now. My date worked out to April 22/71 and my car was built April 27/71.
Good luck
Sheldon
