Thank you very much for this Heads Up article. I am sure the rest of the HEUER community will appreciate the information, I certainly do. It just shows that when having a hobby such as collecting fine timepieces one must do the homework. We are fortunate to have people like Jeff Stein, Paul Gavin, John Cote, to name a few, to part with their knowledge and share it on this website. Thanks to all and all the folks that contribute to this forum. Heinz Rengel.
