I doubt he would have liked it but I'm sure he would have been interested.
There are a lot of surprising things about him, some because they're forgotten and some because he was, like all of us, a man of his times. He mentioned Lugers a lot because, even then, it had been around for a long time and it was relatively common, maybe even as common as Colt .45s (which is a stretch, I know), many of which were brought back after the wars. He was first especially interested in the Colt Single Action Army because at the time, it wasn't an antique and nothing was a reproduction until the Great Western came along, which was even before Navy Arms. He certainly didn't like everything new by any means, including the M1, but he was certainly interested in finding out everything he could about new things.
He was also a man who held his own opinions about things and was not given to going along with the crowd. You might even call him opinionated. He probably didn't think much of people who didn't agree with him either, yet he seemed to have an affinity for what we would call characters and many are mentioned in his books, along with their photographs. I mentioned in another post this morning that we don't seem to tolerate characters too well anymore.
There were a lot of famous gun writers who were his contemporaries but I can't think of any of them who were quite like him.
