Hi fellas, I have 3 Ex4 I have bought back into service over time. There is a few suttle differences. One font has a lesser lip, more rounded, the top of the font is more domed, one bale has cylindrical knerld screw downs, one has longer hex type screw downs and the other has shorter hex screw downs.
That's fantastic mate, congratulations and its great to see 3x EX4 version ones. Not to sure about the globes though.
