OK, now look what you made me do.
I managed to get up to the point where the shutter assembly slides out tonight, but I am going to pause there and pick back up tomorrow.
Oh yeah, when taking the brass plate off of the right side, the small brass pin pictured in my hand fell out. I wonder where THAT goes? I have been trying to be extra careful and taking pictures throughout, but that one blindsided me.
I'm kind of at a loss as how to proceed to get this thing humming again. The curtains are most certainly slow and sticky, but the idea of taking that frame apart fills me with a primal fear.
