Simonds went out of business in the early part of the century, at least according to the disstonian institute. I don't know that much about saws, but I haven't read anything about disston manufacturing saws for the simonds brands. Simonds regarded their saws as better than disston saws from what i can tell, and from the simonds corporate site, there is a notice posted in their carpenter's catalog that just says something along the lines of "hey, we decided to stop making hand saws. This year, we're making circular saws. Thanks!!" (OK, that's not exactly what it says, but you can read the text here: http://www.simonds.cc/company/histor...CompanyHistory )

A seller on ebay can say pretty much whatever they want until someone complains.

Unless the sharpener of a saw was very heavy handed (or employed heavy cutting machines), I'm not sure what I think about the comment of a hobby woodworker wearing a miter box saw short (unless it was such to begin with).
