As for Antlers...I was joking with Horns.It's a a tough room,lol
Stocked To The Fences means the horns go right up to the arse end of the fence balls.
If, behind said arse of the fence balls, there is a 1/4" or so of metal heading back to the stock on both sides...its not stocked to the fences.
Thats how I see it , though Flat Back makes me think of Mandolins...but then I'm a fiddle player.
cheers
