Mom drug it home, the sticker says holiday yet the woman who was giving it away kept saying it was a firestone, and that it was a 26 inch. The s/n looks like it says cy0244 and it has the mexican bendix hub.
The serial number should be either under the bottom bracket or on the side of the head tube. It may start with either a H, W, HIA, or S and like the Huffy chart says, first number is last number of the year made. i.e. H912243, the 9 makes it either a 69' or if it had a tank, maybe a 59' (its not) or a 79' (no). That chainring used mid 60's thru early to mid 70's, when they went to the 5 spoke style, then the 4 spoke style used in the 80's. Neat find and good luck!
