well the SP could show up right at the end if the rumored 1965 start holds...
The first 737-100 made its maiden flight on 9 April 1967 piloted by Brien Wygle and Lew Wallick[5] and entered service in February 1968 with Lufthansa, the first non-American airline to launch a new Boeing aircraft. The 737-200 made its maiden flight on 8 August 1967. Lufthansa was the only significant customer to purchase the 737-100 and only 30 aircraft were ever produced. The lengthened 737-200 was widely preferred and was produced until 1988. The launch customer of the 737-200 was United Airlines. The inaugural flight for United was flown on 28 April 1968 from Chicago O'Hare (ORD) to Grand Rapids, Michigan (GRR). After aircraft #135, a series of improvements were incorporated in to the 737-200. This became known as the 737-200 Advanced, which became the production standard.Quote
So it should be buyable from '67 or '68.
