    HO-211 Hulbert Hinkel Jr.
    From: Robert VanderPol II
    Date: 2018 Apr 19, 20:42 -0700

    Found references to him authoring at least 2 articles in the US Naval Instituted Proceedings Magazine:

    " Longitude by HO 211". April 1935, Vol 61/4/386

    "Additional uses for HO 211" June 1936 Vol. 62/6/400

    Not being inclined to drop $65 to look at the 2 articles I'm trying to find a library with the backlog of issues that include these articles, especially the 2nd.  If anyone has access let me know.
