Greetings All, I'm offering for sale Konrad Knirim's massive two-volume set (a remarkable source for information on European military timepieces) as well as the Whitney book that focuses more on U.S. military timepieces. You can order the two-volume set directly from Konrad for roughly $375 (more info here). My copies are as-new and I'll take $275 for the pair, including shipping (US). The Whitney book typically can be found for around $90. Again, my copy is as-new and I'll take $75 shipped (US). Thanks, OF, for the space.
