So theres no date code for the 7 digit serial numbers for homelite, the only thing we have to go on is Joyce's sales records, her & her husband were homelite dealers for over 50 years and she kept a log book of all the saws they sold, she passed away a few years ago, and we use her log book as an estimated DOM because she logged when they received the saw & when it was sold, so according to Joyce's sales records, 2376902 was received on 5/26/67, sold on 11/14/1967, so that's gotta put your saw in the 67 range. Hope that helps.
