The older book listing for this part is E4744, which you'll still see in some earlier catalogs and on some engines. If you're cross-checking against a parts book from the mid-1960s, that's the number to look for.
Our catalog record shows this tube appearing across a handful of listings from 1964 to 1965. If you're not sure whether this is the correct oiler tube for the crankcase you're working on, give us a call and we'll help confirm before you order.
