Oh, so you know that Hosty wasn't referring to two other rifles...even though that IS what the note says....
How do you know??
Because a) Hosty never said that this referred to two other rifles, Fritz said that it was "two other gentlemen" and both Truly and Caster confirm that there were only 2 rifles -- a Remington single-shot, .22 rifle, and .30-06 sporterized Mauser.
To which your reply will be that everybody is a "damned liar" except you, because you fabricated a story about what a handwritten note means with zero to corroborate your interpretation.
