Thanks all for your warm welcome. Feels like I've finally landed in the right place.
Tim: cant tell you anything about train times, very rarely use them and don't travel much out of Cornwall. Must get out more !! I would guess the sleeper service is still running.
Black Dog: I'm scared you might be right about moving up from 5x4. Did my first contact prints from the first trip out with the camera last night and WOW!
Although there were lots of consignments to the bin, a few of them had that jewel-like quality you don't often get with enlarged negs. ULF here we come !!
