I've remembered that I was originally looking for DD Maksutov's article on his catadioptric telescope published in 1944. Consequently I had a look at the contents of JOSA for 1944 and I believe the actual article in question is:
An Optical Sighting Gauge for the Garand Rifle C. B. SITTERSON and JR. and NORMAN F. BARNES, JOSA, Vol. 34, Iss. 3, pp. *126–126* (1944): http://www.opticsinfobase.org/josa/issue.cfm?volume=34&issue=3 <http://www.opticsinfobase.org/josa/issue.cfm?volume=34&issue=3> It was probably intended more as an acceptance test by the army.
