12-Cab C60L & More

[Phil Waterman]

Reason I ask about a picture of the engine serial number is that I've encountered two engines without any serial number stamped next to the distributer or the second serial number under the valve train side cover.

I understand that this generally indicates a replacement engine and that the original serial number would then be stamped with an indication of replacement. But in practice the blank engines didn't get stamped at all.

Now as to your numbers I've been back through Peter Ford Infoex and find nothing similar to your number. Peter's note on Engine Serial Number
"216-inch engines:
Two letters designating Productions variations (AR through ZR) followed by seven numbers."

The picture is of my 1941 C60L and shows both number locations

What is the casting number on the block, should be above and behind the starter?
