[sel498]

I have had this guitar for about 10 yrs, and my buddy had it before him and his brother had it before him, The serial number lokking through the soundhole towards the neck is 947185 . and i found another on the inside bottom of the body that is 440324 . Please Help. I have posted a few pics of it below, and yes I have refinished the neck, headstock, and body but left the front original with the exception of the signatures. The first number doesnt make sense, but the second one,(after multiole searches) leads me to believe it was made on March 24th, 1974 or 1984, but i thought they quit making them in 1974-75? Please help
