"CE" BLOCKS ---- Understanding this code

[L34Pace]

Here's a new development that those with CE blocks might want to check out. It seems that an assembly code was stamped on the blocks when applicable. You need to remove the starter to view it as its on the flat surface of the flange. It seems to consist of the month and year only excluding the day. I've found them on both Tonawanda and Flint blocks.
