Ah, okay, I had to look around a bit, but I found some examples of this.
ASH is a FAA Contract Tower, and it looks like MTN is a contract tower
part of the time, and a non-federal control tower some of the other time.
At least, that's my interpretation of listing for MTN ... I wonder why
that is?


It has to be an error. Note that the hours of operation as an FCT coincide
with the Class D hours. I suspect this was an NFCT that became an FCT, and
the "NFCT" mysteriously remained in the A/FD.
