I'm trying to date a Low Head and found the term "Fingerprint Head" being used. Does having the fingerprint boss on the head in anyway help date them. This head I'm looking at has the fingerprint boss on the back, it has Ford script and Made in the USA
Does that in anyway help date it.
Thanks,
Scott
