In 1961 Rorton was looking to re-engine the RO.139 due to the Rocor Mars VII Inline IV going out of production the next year. Rorton decided on the Union U-120 a new 120hp Inline IV, this along with some other smaller changes gave rise to the b model, it was built from 1962 to 1968 when the RO.139 ended production entirely. has the same features as the RO.139a but anyways hope you Enjoy!
