I'm not sure on your frame.
A few years ago I had either a Shelby, Iver, or Pierce with the slot in the
BB housing.
You might try holding a strong lite and turning the crank and see if there
is a notch/hole in a sleeve that's threaded on the crank.
My crank was two pieces held together by the threaded sleeve and when I put
wedge/srewdriver/drift in the slot/hole and twisted the crank it unscrewed
and came apart to each side and pulled out from the cups.
You might give that a try and see what you have.
Otis' crank came apart from the locknut side and then the otherside was a
one piece take out .
Otis may give you a more detailed note.
