Nah, sounds like a typical builder-grade window with a single-track
storm window on the outside. I'll bet the top inner window USED to slide
down, but with the cheapo fixed storm window in front of it, nobody has
bothered for the last 2 or 3 repaints, and it is just stuck in place.
I'm assuming a wood-frame window on the inside part, of course. There
were all sorts of weird metal-frame windows installed back before people
realized how much cold they brought into the room.

It's sadly a metal frame window. It is a cheap unit, and they
aren't made any more. Probably because they suck. We're running into
big costs replacing a missing screen on the front window so we wanted
to replace the glass in this side window ourselves. It's all one
unit, not a regular window plus separate storm window. The window
does have 2 top panes, one inside and one out, but they don't move and
were not intended to move at any time.
