100% agreement. Any time I get the need for a DR fix, I pull out my first decade 20th Century 476 Droplock and gaze on it for a while before turning it over to take out the locks and play with them a bit. (Yes, I DO know how to reset them, no I do NOT use a pliers or otherwise force them. Yes, I had a longtime WR owner school me very carefully in how to do it. And no, I did NOT get it right the first time, the second, . . . ) A brilliant bit of engineering, along with several others WR was responsible for. And, also most fortunately, my 476 has no animals, just lovely scrolls, etc. Dave
