Good source for the small fold-able window parts that open and hold windows?

[KenEhresman]

is Prevost the only source?

still looking for that one bathroom lamp shade too :-) if anyone remembers

If you are talking about the Prevost awning windows, then your choices are Prevost or a junkyard.

For the shade, have you tried Parliament Coach or Donnie Myers Luxury Coach?
