The older stuff is upper mid range in my opinion. US union made as you can see from the Rutgers stamp. The leather is generally not as plasticky as Dexter or Mason, and the stitching on the soles is typically inset a little deeper for longer wear. Not quite on the same level as old Florsheim or Hanover, perhaps just below Allen Edmonds. They are still a product of the good ole days, and definitely built to last. They remind me a lot of the Alden Foot Balance line in construction.
I've even seen a pair in Shell Cordovan and some made in England pairs before, not sure who made them.
