Oklahoma meat cleaver with the "C" font

[bugo]

I spotted this meat cleaver on WB Skelly Drive just west of Lewis Avenue.  All of the new OK 66 cleavers around the newly opened Lewis Avenue bridge over I-44 are the same style, using the "C" font instead of the "D" font. 

How many varieties of the cleaver are there now?  Most 3 digit cleavers have the "B" font but I've seen 3 digit cleavers with the "D" font.  These are the first cleavers with the "C" font that I think I've ever seen.
