    Re: Puzzled by Douglas Protractor Instructions

    I found this on the web, do not know why they use the name Monkton Protractor.  Interesting is to use it also as stationpointer.  regards, HermanD

    Herman, A quick ‘Google Images’ search for ‘Douglas Protractor’ will show that a number of companies have marketed their own version of the basic Douglas protractor modified to a greater or lesser extent. 

    Some don’t even have the courtesy to include ‘Douglas’ in the title.  Yes, you could use one as a station pointer, but you wouldn’t cover much area with the five inch square version.  You can use any transparent film as a makeshift station pointer.  We just used tracing paper to score radar photographs.  DaveP
