I agree that I don't think 'pre-war' in and of itself makes those machines any more desirable. As Cari says, they are 15-91's and are just great machines regardless.
The top one in the cabinet does look particularly clean to me. Just depends on how you feel about the cabinet not having a top. I don't think $60 is a bad price for that machine regardless of the cabinet damage. Just depends on how important that is to you.
