I also have a frost king sr# 16417 Any know of a ser. no list to age itLooking through back-issues of the "Stationary Engine" magazine for info on this engine and I found a picture of one a few years back. The serial number is 27855 and the owner says that it is 1916. That would make mine really early (16525 ). Does anyone have one around that date with a definite age provenance, please?
