Topic: Suspicious C8OF-D carburetor

[WT8095]

This carb is currently posted on ebay. The date code doesn't make sense - February of 1967? For a C8OF? Even more strange - the month should be a number, not a letter.

Is this a fake, an error, or just something unusual that I haven't heard of before?

It's a Holley carburetor. It may be explained in Jeff's date code posting.

I thought ford application Holley  carb dates were 3 numbers. It may read 764- 1967 June 4th week.

Something odd going on here - good catch with the letter as Holley's date pattern didn't include a letter

Do have pictures of carbs identified as reproductions having a letter in the three digit date code

Depends when it was made

Looks like the only thing odd going on here is inside my head!   

As John pointed out, the month is 0-9 Jan through Oct, then A for Nov and B for Dec. I have a couple of January '68 carbs, but apparently I've never encountered a Nov or Dec carb before, and I didn't stop and think about how you represent twelve months with only ten digits.
