No FCTM, no FCOM.
I've flown for two 737 operators and didn't know what those were until I got to a large international operator and they handed me the Boeing manuals in class.
When asked why we can't have access to the Boeing manuals:
"It's not that we don't want to you have them . . . it's just that we . . . [don't want you to have them]."
And when asked why we don't follow the Boeing manuals, it's usually along the lines of "for commonality."
That commonality seems to be with planes that we long since retired.
