The first antimagnetic Railmaster, Reference 2777-2, was produced in 1955. It is a civilian successor to the 1953 military antimagnetic, the RAF Reference 2777-1. The reference 2914-1 Railmaster was produced in 1957,as was the 2913-1 Seamaster300 and 2915-1 Speedmaster.
Therefore, IMHO, the new Railmaster LE is the 60th Anniversary of the 2914-1, which was actually the 2nd generation of Railmaster.
