"2ND" casting tags ...

if you own an Oliver/WHITE, they're all over your tractor. typically PNs, but sometimes other things.
Casting numbers (numbers that are raised and cast onto a component) were often stamped metal tags which were fastened onto the patterns at the foundry to identify the raw castings when they were removed from the molds. This allowed tracking as a casting moved through the manufacturing process. That same casting number could be found on hundred, even thousands of a given casting that might be used on many various machines. The same casting could be machined different for various uses.

A casting number may or may not be a part number. A part number would be assigned based on the machining done. Generally, a finished part number would be stamped into a component, after machining, if any marking was done. Casting numbers are often referenced to determine which part number applies due to changes during production runs. Casting numbers on water pump housings are sometimes referenced to get the correct water pump part number as one example.

I guess I need to be clearer for you. I've owned plenty of Olivers and I'm very familiar with my Oliver casting numbers, date codes, etc. on the tractors. Casting "tags" is a term I've never heard. A casting number with a "2nd" on it I've never heard of or seen on any Oliver.

no, it was abundantly clear with your first reply that you don't know.

correct. "tag" delineates the raised from sunken, or stamped, identifiers in cast parts.
 
I sure don't know, but is there any chance that it would be a code for which factory it came from? Charles City, South Bend, Springfield, Battle Creek?
 
I don't know either. But I was told by one person it is the date that the cast was made. But where he got it, who knows. I have hauled a lot of iron into foundry's that make cast iron, but never asked anyone.

I want to clear this up. The guy that told me this , is not on here or YT.

It's not a matter of I don't know, it only sounds like our nomenclature is different. Now I know you use the term "tag" to describe a casting. "Tag" is redundant to me, unless it attaches.

How about a picture of the "2nd" you're referring to?

Some casting numbers designate the casting. Some manufacturers/foundries cast codes, such as the date the casting was poured along with casting ID numbers. Some identify the foundry with a cast number or symbol.

What exactly are you looking for?

the question of my OP--what did the "2ND" casting tag signify? (specifically, if anyone knows.)
 

Then my guess would be a replacement block, and I don't have one to look at. Our 1955 was sold and the 1855 was definitely not a replacement as it was the old style and had an extra window to breathe.

If it was my tractor I would get the build card and compare the engine serial numbers.

that is a reasonable guess; thank you. and, i have wondered about that possibility before ... this is nearly the last 1974 1955, and the date tag on the block behind the starter is blank!

it also has head studs instead of bolts, except for the rocker shaft oil delivery and 2 lifting bolts next to rear injectors.
