Can't say for sure but they did have a decent section of cameras that ranged from poleroid era back to ones that look to be late 1800s or early 1900s.
I've never seen any plate cameras all the times I've been there but inventory is always changing. Theres usually a few bellows "pocket" cameras around, a few "brownies", and the occasional Polaroid or Instamatic here and there.
