    Re: U-boat Celestial Navigation WWII

    Hi Brad, I will now start investigating the MHR-1 in earnest, starting by reviewing the discussions on NavList.  I have read the excellent paper by Ronald R.W. van Riet. This will be a challenge since as yet I have not found any WWII era documentation on the MHR-1 beyond the brief instructions afixed to the device.  One would imagine there would have been at least a phamplet if not a book describing how to use it along with some sample problems.  If anyone knows of such a document, please let me know.  Additionally, with my limited experience it will be hard to move step by step through a sight reduction without being able to hold one in my hands.  Once I get familiar with the information at hand, perhaps I can find one not too far from where I live and work with it. Jerry
