After another evenings work the GWT mk3 TGS is now finished, sort of, when refitting the roof the plastic was very brittle and shattered.
Trying to glue it together didn’t get a satisfactory result, so I will remove the Hornby glazing and fit a new roof from a Lima mk3

I need to take some dimensions to see if it’s viable, but an alternative approach would be to use a Hornby mk3 roof chopped off its sides and glued in place, which would get a better match with the rest of the reje
