Deletion of Flashboard

Comment: Article fails basic  as all articles require significant coverage in reliable sources that are independent of the subject. I am at a loss as to where in depth coverage exists as searches of all Google engines, Highbeam, NYT, Bing and dictionaries are providing hits for Dam flashboards or a flashboard network and none for this "Flashboard". A search of Henry Harold Hemming, a Canadian Reconnaissance Officer, did turn up that he devised a flash spotting system referred to as "Flash Buzzer System" (see {{cite book|title=World War I Battlefield Artillery Tactics|url=https://books.google.com/books?id=BrzvCwAAQBAJ&pg=PT62&lpg=PT62&dq=h.h.hemming&source=bl&ots=l5LiZmp_3M&sig=0_0iVHM35uNIznGliqQp_uzU9wI&hl=en&sa=X&ved=0ahUKEwj47tv7mJDSAhVK-mMKHfhKAh04ChDoAQgmMAM#v=onepage&q=h.h.hemming&f=false}}) although I can find no instances where it is referred to as "flashboard". I suspect that this is the device that the article is referring to since the first source listed in article was co-authored by Mr. Hemmings. If that is the case, I would have no objection to a redirect to Flash spotting
