Swiss test sample probably not

I haven't found any record of AAC exporting test guns to Switzerland nor have I found any indication that the AAC guns were twin-mounted, except in the M-H tank. This is not to exclude the possibility that AAC guns were not ultimately tested in this configuration, simply that no record exists of such a test.

I have a video of an AAC promotional film, approximately 15-30 minutes long. Quite interesting from the standpoint of the number of facilities owned or used by AAC. Includes tests of the AAC anti-aircraft gun at the New Jersey test site, manufacture of bombs and ammo for the 37-mm guns, etc.

My book manuscript writing (about AAC and the private arms dealers between World War I and II) continues. It is now somewhat over 400 pages, including Appendices.

Many thanks to all who have helped. I look forward to receiving any additional info that anyone cares to share.
