Looking for APG Dec 39 test Report

[tuskinventor 0]

Does anyone have a copy of the December 1939 test report conducted at Aberdeen Proving Grounds?  I am specifically trying to find the name of the shooters of test #5 and #8 of the test.  Why?  I have an operators manual inscribed by Mr Johnson on Dec 26th to a Mr Henry Lawrence congratulating him on his accuracy when firing the rifle—suspect he might have been a shooter/tester at APG during this test. Thanks in advance.
