Very interesting collection, and nicely displayed. Thanks for sharing it.
As an old git I really think you should cease and desist from electocuting Dave. Are you trying to turn base metal into gold? You will just make his fine body a little more grey. Why not start a new trench for all us oldies, it's a lot cheaper than the coop.
I've found a way of dealing with my lack of display space and unwanted 'phone calls in one go. A gentleman from Bombay called me recently asking if I would like to have a patio built, I managed to keep him on the 'phone for nearly twenty minutes before revealing that I live in a second floor flat, don't think he will bother me again.
