340 timing cover

Does anyone have an original 68 273, 318, or 340 with original timing marks cast in the timing cover?

Bill, just purchased the timing cover from me, in the above picture.
Went and got it off the storage shelving, in the garage.
Well, come to find out it's a 68 cover, with the timing tab cast into it.
Has the 68 right in the front of it.
So i had one too, all this time. Now it's going to a good new home in NM.
