Hello everyone.
I have a question about ball nuts.
The image is a 242B Seafoam ball nut, but I saw the groove indicated by the arrow for the first time. What is this difference? Mistake in the factory?

Thank you,

I don’t know.  My A46 all seafoam has the smooth edge.

I have a few of those too. They may have been  packaged parts for replacement, as some of them came in the little bags right from Toronto.

Thanks everyone for the response. Maybe the first lot came with a lot of Canadian-made 242A, B lanterns, or it could be a replacement. It is a great discovery for me. The same ball nut was from Canada. Thanks for posting the Steve photo.

Yep, I think it's a Canadian thing, and not confined to Canadian seafoam painted lanterns, or any particular models.
I went and checked all my Canadian 242, 247, and 249, and Australian 242B and 249 series lanterns, with that style of vent nut, and found about 20 vent nuts out of 60 lanterns without the vertical striations on the bottom flare. That vent nut type appeared sporadically across that range of lanterns, but with no defined pattern.
I also found some of the ball type vent nuts on both Canadian and USA lanterns without the bottom striations as well, and some with them. Again no pattern emerged, between models.

Here is a pic of some.

Hello Keith,
Thanks for the reply. Thank you for the attached photo. It is very easy to understand. There were also 247,249 series other than 242B, but there is certainly no definition. Neither 247 nor 249 in Canada I have has vertical striations on the bottom flare. It is very interesting.

That’s pretty funny. Parts may be harder to let go of than lanterns and lamps!

To me a lamp without a shade is creepy!

some of those were sold as replacements in Canada-they came 2 to a pack and had the spline knurl on the lower flange.

Thank you for contacting me. I was convinced.

I may be wrong for this specific case but the additional straight knurling on the lower flange is not a surprising thing.
I've had similarly shaped and knurled brass ball nuts being machined in a local machine shop here. Its actually easier for the machinist to make the tiny piece with the knurling all the way length-wise and cutting the groove after that, rather than having the upper side knurled but leaving the bottom flange smooth. One of the reasons: clearance of the knurling tool from a rotating chuck can be troublesome or tricky since you can't leave too much extension on the relatively small-diameter brass stock out from the jaws of the chuck during a high pressure knurling process.
Dean would know this very well.
