Update, pulled off side covers and on it has number 465 18739. From all my searching online I’m guessing the two carry handles on each side are added later on. The Atwood site doesn’t show a prefix 465 but it referenced Firestone and a 7.5 motor. It does appear to have originally had a recoil pull shroud on it there are grooves that look like something belongs there but now just a pull rope. Poured some liquid wrench in the plug holes to see if I can free it up. Will post pictures as I tear down and clean up progress.
