pretty much all done with the layer style tools - gave it a bevel and an overlay, flattened the image - used stroke with a finish on that, flattened again and added shadow.
with a bit of time the shadow could be played with to make it look like 3d letters rather than shadow, but without having the correct font i wasn't going to waste any further time on it.
if you can find a name of the font or a close enough match that you'd be happy with i'll have another play.
