Mike,
I have no clue if it will sell at that price or not,it only takes one buyer and certainly do wish you luck.Two things I really do think would help is more pictures,especially of the barrels and the flats-I am not good at taking them either but you need more then one to sell that gun IMO.
The second is more info,weight,barrel wall thickness,rib inscription.

Good luck I hope it sells for ya and you find your Purdey.
