Rough Pricing for Parker 12ga?

[mattsolar]

I've had my eye on a nice double-barrel for a while and I *think* a nice one just popped up that I could get my hands on. Unfortunately, this is all I know about it: It's a Parker Trojan 12ga, serial # beginning 220.

Before I take the drive to go check it out I was hoping someone might be able to give me some [very rough] direction on it's approximate value and/or what to look for when inspecting the gun in person. Based on pricing available at Cabelas (http://www.cabelas.com/guns-1/11657.shtml) they have then in the $800 to $2,500 range - obviously a huge discrepancy.

Thanks in advance,
Matt
