Dahone,
Yeah, I was wondering about that too! I have an email inquiry into Angel's to see what records they might have. Also, I don't know if, back in the day when B&N was separate, if even THEY made all their own stuff. A lot of prop/costumiers make some, and buy a LOT.
With the reinforced parts, the attention to detail, and the volume of available nondescript Chels boots... I just really wonder.
