There would have been a time...maybe 1955 or 1960 or 1970 when those records got little respect at Remington. It is very easy to imagine some guy a Remington - maybe an exec or maybe a clerk - getting asked to copy a record on a gun and having him tell the guy, "Oh hell, just take the whole book with ya".
For another example, I worked at Westinghouse in the late 80's and some dumb lady they hired to organize the record vault decided to toss out a bunch of 'those old smelly files'. A couple weeks later, long after the dumpster was gone, a few others found out and it came to light she had tossed out many historical records including original patent papers and other other documents penned by George Westinghouse himself.
