As mentioned in my last post the pantograph will be a former Class 390 Pantograph. This looks very similar, I've now fitted it, and now plotting the holes for fuses.
I've already done the main modifications but forgot to post on here, but I've cut down the space to hold the Pantograph for the Serco Test Coach 6 "Prometheus" which was scrapped around 2004/5
I think! Here's what it started like and now looks like! It'll be tired with a 390 pantograph and fuses, with Fox transfers.
