Hey Greg, Sounds like "Jealousy Windows". I have some of these on my camper....glass louvers you can open and close with a crank like a casement window. I like them on the camper as they will deflect the rain and still provide venting. Rare on exterior house doors especially these days when people want thermopane glass.
Try Anderson windows.....I read soemwhere they may have them.
Good Luck.
Bart
