Very cool bike there!
I was holding out much hope that basic lubrication would help, or that one spring had merely failed (sigh).
I'm assuming you can get those shoes re-lined, and they'll perhaps want to know the exact ID of the drum to determine the lining thickness, maybe even want to have the backing plate assembly at hand.
Good luck with it, and hoping the braking power comes up to a contemporary level!
