Thinking about making an offer on a 28 gauge, but.......

[Michael Pescatore]

Greetings,
My name is Mike and I'm located in Tucson, AZ. I signed up this morning, so I'm a brand new to this site and to Parkers in general. I'm usually found on the Shotgun World Winchester forum, reading and posting about model 12s, 21s and 42s, but someone I know has a 28 gauge Parker and he's thinking of letting it go.
I know very little about Parkers, never having owned one, but I've read that the 28 gauge is somewhat rare. I've seen it twice, and I took a few pictures of it. It appears to be in very nice shape, having been restored at some point.
It is an O frame with 28 inch barrels. My bore gauge read .548 on both barrels and they are like mirrors. The left choke came in at 19 thou and the right at 11 or so. LOP is 14" from the front trigger and 13 and change from the rear, with a widow's peak dog's head plate and grip cap. I did not measure the chamber length. The serial number is 106284. It points beautifully, w/double triggers and I'd guesstimate the weight at 6 pounds or so.
I'm thinking I might make an offer on the gun, but I'm more than slightly out of my depth here. The trigger plate screws look slightly buggered. I'm not sure if the barrel has been trimmed/cut, and I don't know if the blued top lever and safety should be case colored instead.
I've seen some sales at auction houses on line for similar Parkers for anywhere between 8 to 13 K. The owner hasn't come up with a price as of yet. So I thought I'd post some pictures of it here to get an better idea of what I'm looking at. Any guidance or opinions would be greatly appreciated.
