Hi Janey,
My Weed came with only one foot but many machines of this era came with different feet for hemming and such. The foot would be removed and swapped for another. The manual talks of changing the foot for hemming. This one does look like a multi-purpose foot.
To remove the shuttle I turn the wheel until the shuttle is in the most forward position. It is almost under the needleplate. I can put my fingernail in the slot near the back and lift it out allowing the pointed nose to dip forward while lifting. The bobbin is held in the shuttle by a spring loaded circle at the nose (pointed) end. Mine was gunky and frozen when I got it. Oiling and gently pushing down on the circle pad with a toothpick finally released the bobbin.
I can't wait to see your beauty as it comes along. It always makes me happy to see these lovely oldies brought back to life!
