Going back to the kit topic , I occasionally look for 7mm loco kits that have been abandoned and have , in the past , got some superb bargains. For example last year I picked up a LNWR precursor tank which just required painting and brake gear doing for a shade over £100. Took me 4 hours to get it into traffic.
One strange thing that I've noticed is when a 7mm loco is advertised,invariably it is complete but never with any brake gear! I've never been able to fathom this!
