The Bachmann Jubilee is a SFB model which covers the class up to 45664 after which all engines had Long Fireboxes LFB.
Barrow Road had an allocation of 9 Jubilees up to September 1961 when all the SFB engines were transferred to Shrewsbury leaving LFB versions, Trafalgar, Barfleur and Leander remaining.
I have converted a number of the SFB models to P4 and finally decided to have a go at converting one to a LFB model.
45562 was the donor along with the firebox and part of the boiler from an old Mainline model
The above photo shows the cab, footplate and boiler/firebox to the right of the nameplate of the SFB model with the Mainline part placed in between.
