Almost certainly hand made. First the bowl was made in a flatbottomed conical mould, then the stem attached; stem and foot were made in a single piece and finished in a clapper (a wooden implement to make it smooth, even and circular). Clappers came into use after the 1870s, so on no account does it predate that, but you had already figured out it was modern. I can tell - not just from the photograph but because I have that exact glass - unfortunately without fox. It gives a high clear tone when tapped but it is no crystal - it is a semicrystal, so it is probably British or Czech. Also, if you see a fox - look for Brits or Bohemians (cherchez la vixen!)
The "N. ORR '68" does not have to be a signature - it could be after an engraving by Nathaniel Orr, who was a most prolific illustrator in the 19th century.
ps. Sorry to hear about your maxident - but if I were you I'd blame it on hot glass....
