I do beleive he has captured the true condition of these run down loco's in their last years of service and yes before you say anything, my layout and modellers licensce allow's me to run the head lights in the 1960's. I like the look of them and that's how it will be on my layout. I know the VR appeared to have lost them all by the end of the Narrow Gauge and most of the historical photo's show only marker lamps as head lights or nothing at all.
The beauty of the hobby is you can do what ever you like and no body should be offended ( except the rivet counters ) because its your railway. If we tried to make everything exact we would get that frustrated I think, well I would just explode.
