I'm purchasing a rather complicated shield for my two-weapon fighting dwarf. It's a Spiked Heavy Metal Shield of Bashing +1 Armor/+1 Weapon. The description of the Bashing ability says...

Bashing
A shield with this special ability is designed to perform a shield bash. A bashing shield deals damage as if it were a weapon of two size categories larger (a Medium light shield thus deals 1d6 points of damage and a Medium heavy shield deals 1d8 points of damage). The shield acts as a +1 weapon when used to bash. (Only light and heavy shields can have this ability.)
Moderate transmutation; CL 8th; Craft Magic Arms and Armor, bull’s strength; Price +1 bonus.
So my question is this: Since the shield acts as a +1 weapon, what does that mean if I want to upgrade it by adding more magical weapon enhancement? I want +1 Weapon, so...
A) It doesn't stack, I know that. So it's not just a +2 Weapon.
B) Does it mean that the +1 Weapon portion of Bashing doesn't apply, only the increased damage die? This makes some sense, because Bashing gives it +1 Weapon Enhancement and Weapon gives it +1 Weapon Enhancement, which simply don't stack, leaving just a plain ol' +1 Weapon.
C) Or does it mean that the shield has a +1 weapon bonus already, and to get a +2 weapon bonus I must pay the 6000gp difference? This would make the most sense, but the costs don't add up. Well, actually... You pay 3000gp for Bashing, so maybe that
is the same as getting a 2000gp +1 Weapon Enhancement, plus a 1000gp damage die increase.
I'm tempted to choose the third option, but I'm not sure.
