Re: Strange Head Casting Date

The "Y123" is on a brass tag that inserts into the pattern and is secured by the two slotted head screws. Flat heads for first shift and round heads for second shift. I don't think that it's a coincidence that the numerical date is "123". I'd guess that someone was casting a bunch of aftermarket or over the counter heads and filled the date slot with a generic "123" date.
