Damn! I thought it was Val.In Dolf's Vol I, there are still pictures from this same date. The same personnel and locations are seen as in the video, the manufacture of 1917 water cooled guns. The stills are credited to Roy Marcot, Historian, Remington Society of America. So, this would appear to be the Remington Arms Bridgeport Works, Bridgeport, CT. The stills peg the date as April 25, 1918. This is very early production, no guns delivered by any factory as yet. The men in uniform are likely the Ordnance Dept Assistant Inspectors of Ordnance, and one may be Capt. L.E. Biggs. His initials are on the early production guns from Remington, before Major E.E. Chapman took over that position. I have documented L.E.B. initials at serial 418xx range, and E.E.C. as early as 438xx. These are right in the middle of the first series of numbers assigned to Remington, 367xx to 467xx, so we have a 2000 gun range where the change in inspectors is known to have taken place, supposedly about August of 1918, according to Dolf.
Just having seen Mr.Maim's photos added, that is definitely Val A. Browning in the lower four pics. The top pic is a Mr. Best, at the Remington Arms Bridgeport Works, same gentleman seen on the video. I came darn close to getting to meet Val Browning in Ogden, about 1984. They told me he had attended our event two years earlier (if only I'd known!), and I tried to see if the staff could connect me to the right people to meet him. This was at the Performing Arts facility he funded, named after him still, but I didn't have the juice to pull off an introduction.
