I have an early Kodak/Century that is a "full plate" camera, a little larger than the 5x7 at 6" x 8", It has a reducing back for 5x7. nice size, mine was little used apparently and was in immaculate condition. Only drawback is that it is not an 8x10 camera.

Any of the Century or Kodak cameras will be built about the same, Ansco I would toss in with B&J. Look for cameras that come with extra lens boards, Extension rails, tripod blocks --make sure the rails will lock into position... no missing screws... no bent brass...no split or cracked wood... check that the back doesn't look like it has been modified or taken apart and that it will fit solid both horizontally and vertically.
