I've finally found a suitable photo of a radiator badge for the Simplex, so it was into photosuite - resize - print - cut out
and stick on!
While she was on the bench, along with the kit I'd been using on the Locolines Corris, I finally added a top & bottom hose to the rad, an exhaust and a bit more "clutter".
That's another round tuit off the list
(BTW the exhaust is brass pipe fixed to the bonnet with a self tapper, when I loosened the screw slightly, the exhaust shakes very prototypically as she moves along the track )
