Unique gun, agreed that it may not be a “Super Fox” by serialization but is definitely built/bored that way. Would be interesting to measure frame size to see if it has the wider/deeper frame that is equipped on a Super/Wildfowler. Repaired wrist does not equate to “mint, original condition” but it is a unique gun. I have no idea how one puts a value on a gun like that. List high and get as much for it as you can I guess. I like it!
What makes you write its built-bored like a Super?
There are some postings on the fox wsite written shortly after the southern. The fellow who started posting there seems to have been charmed at the southern by the owner. Nice fox for what it is.
