I just found (Saturday) a US Navy nautical slide rule, marked "U.S. Navy bureau of Ships, Mark 1, Mod.O" dated 1959. Its a very neat device for time -distance speed calculations. It has two scales, one for nautical miles travelled and one for yards traavelled. I did a quick search online and found that new ones are available , as stated in other posts, for about $20. I got mine for $5 but thats the luck of the draw. At any rate, I havent used it in a mission yet but it will definately be useful. Joe S
