That is a pretty gun, and in very good condition it appears. But, with all due respect, it is not a true target gun with that straight grip, pretty as it is. There is just no way that a straight gripped gun will give you the control, in recoil, that a pistol gripped gun will. Absolute control is necessary for that second shot, and half the birds in a round are second shot birds. Loss of control means you will drop more second birds than you should.
You can find a 30" BSS, unaltered, for $1500 or less with just a little work. And personally, I would not pay a dime more for one with screw-ins. All my 12 ga. sporting comp guns are fixed choked. But, that's a topic for another thread.

Stan,
While I'll always consider you "The Man",
I have found no problem with second shots using an English stock.
I won Summer Skeet League with this BSS and had no problem with pairs.
I've also shot Sporting and even hunted Band-tailed Pigeons using this one of a kind BSS. 99%
