Greetings Mike, I have built 2 3 1/2 in gauge Jubilee’s and they are both fine runners. Now I am building a 3rd in 71/4 in and that is going ok with most of the bits laser cut by MEL who produce a lot of time saving parts for this design.
It was written up in ME from April1958 with the last episode 26th Nov 1959.
Regards
Brian Baker
