Thanks Nick, you've hit on one of my big worries. I've always expected to give my son (and therefore my grandchildren) all my collections of trains and boats and steam engines and pocket watches and woodworking equipment but so far the fire is just smoldering for him as he is into his work big time. The grandkids are hit and miss as I would expect at their age but I still hold out hope for the future - otherwise someone, hopefully real aficionados, will probably get some bargains down the road.
