441 lube pots

So when I purchased my Ferdco Pro 2000, it came with 2 lube pots.  I thought one was maybe a spare, so I left it in the garage as I hadn't gotten around to cleaning it.  last weekend, while cleaning the garage, I came across the spare lube pot and brought it into the house. I was just looking at it, and noticed for the first time that they are not identical, but more like mirror images of each other.

Having never used a lube pot, I can only make a wild guess... One was used for sewing, and the other was for lubing the thread while winding the bobbin.  How far off am I? What is each pot really used for?  Also if anyone has any good links to how the lube pots are used, I would be interested.

Lots of views but no replies. Are people as stumped as I am?  I was able to finally find a photo of how these are threaded, but it still leaves questions.

From what I found, looking at the photo below, the thread comes off the spool on the spool stand through the hole at the bottom of the lid, through the hole in the stem that protrudes from down from the lid and then out the hole at the top of the lid.  From there it goes through the eyelet on the top of the lid and then is threaded normally.

So what are the machined metal cylinders that protrude from the front and the side of the pot?  I unscrewed the cap from one of the pots and placed it in the photo.  You can see a rubber cone shaped grommet on the part the sits inside of the cylinder.  I would think that these are rubber wipers and that the thread should come out of these instead. Once again one for sewing, and one for lubing your bobbin thread. If that is the case, why does the second pot (one on the right in the first photo above) have a cylinder that comes off the back of the pot and not the front? Surely someone has to know.

I have the original Ferdco Pro 2000 Owner’s Manual that came with the sewing machine and decided to read it from front to back.  The only mention in the entire manual on the wax pot is what is listed below and is found in the accessories list.

So, I can only conclude that the metal cylinders coming off the front and left side of the wax/lube pot are indeed wipers to remove excess wax/lube from the thread as it passes through the pot.  The one on the left is obviously for sewing, and the one on the front is for winding the bobbin.

Unfortunately, this still does not explain why the second one has a stripper coming off the back and not the front.  The only thing I can think of is that this was an error in manufacturing. When the original owner installed it and noted the stripper was on the wrong side, Ferdco sent him a replacement with the correct orientation, although the spare with the wrong orientation is the only one that looks used.
