Yes, I think mine is a special case too. But not special enough to not be in that figure / picture from my last post.. The bobbin is definitely 22mm x 7.2mm and it definitly goes with the case. Perfect fit! But if one looks carefully, the bobbin drop (I hope you mean the holder and release) is actually a combination of the old style and the newer style. It has the older style release lever but the new style holder with the horizontal bar visible in the hole. And of course, the bobbin case seems to be a combination of the older style without the spring but with the spring added. And the all important slot missing. All very interesting.

I am now wondering if the bobbin dimensions were also changed at this point or later. Old style bobbins were 1.00" (25.4mm) in diameter by .245" (6.22mm) thick. New style were .866" (22mm) i8n diameter by .278" (7.06mm) thick. Note that in the manual picture the arrow shows the bobbin rotating in one direction & the thread coming out from under the tension spring in the other direction. In this case the bobbin would be rotating away from you when in the machine while the thread would come off toward you. This reversal of thread direction is almost universal in round bobbin machines. In the picture of your actual bobbin in the case it appears to be a good fit so likely the proper bobbin is being used for the case. You might want to check the clearance to insure there is enough for the needle thread to pass around the case without binding. If the holder is too tight against the case it will not allow the needle thread to pass around the bobbin after being picked up by the hook. This can be adjusted by removing the holder & noting the little screw in the base facing the machine. This screw has two flats on the end & by turning it in or out the position can be adjusted & it will then come to a positive stop when it is removed for cleaning etc. This of course will not help in the threading of the case, but can help in the actual sewing. I am thinking that you possibly have on of the earliest of the #8's with the tension spring on the case & that it was quickly modified. W&W did make little changes along. I have a very early D-9 (low SN for them) on which the bobbin threads opposite than any other I have ever seen nor have I found a manual which showed this opposite threading, but it is obvious when comparing it with others. Wish you were a lot closer to me, I would like to set down with you & the machine & look it over real good & see what we could figure out. Do check & let me know what size bobbins this machine uses.
