I have a few Canadians lanterns they for some reason I was looking at the vents nuts and found some really interesting differences. I wish someone could reproduce the one in the middle, when I got my 249 lantern was like that, vent stud was steel very rusted and vent nut was stuck in there looks like previous owner tried some pliers on it. All I did was quench, quench until came off; had to buy a new steel vent stud for my 249 and wearing the same vent nut, wish I could find a sale one.
First vent nut pictured is from a 242k and look at it is a bit shorter, knurled rim is wider that the other two. Last one in the picture is from a 242b and is the most popular one, they are either nickel or bare brass
