5470409 master cylinder EB stamp???
 

Opinions on this 5470409 master cylinders EB stamp? Any concerns? Looks like stamped striked multiple times or over top another?

it looks like a good stamp to me. I compared it to my 70 z28 and 70 L78 camaros. It looks just like them other than the 2nd overstamp.

Looking for a thread that has application codes for "409" Master Cylinder

EB = 70 Camaro
BB = 70 Chevelle

CF = ????????

What about this one? It's on my 70Z. It has the same stamp bounce thing going on. I believe it's an original finish master cylinder.

Here's another original 70 EB stamp I owned at one time with what appears to me being the same font as the original one on my current 70 Z28.

Wanting to know if there is any reason to invest in restoring a 409 MC with a CF stamping
(has bleeders)

And I have another 409 with Bleeders with No Machined Pad nor Any Stamping

After mid 72 they are on the first boss -
I believe that beginning in 70 the assembly date is on the first machined boss as well, it is on my 546 corvette master cylinder.

Here is the one off my brother's 01A 73 Z.
CS - 1973 Camaro
Stamped on the first boss - approx 2mm tall 356th day of 1972.

FORMAT -
Application code - last number of year - day of the year
