[Christopher Barker]

I am trying to get as much info as possible on this SXS Parker. The case shows colors unlike anything I have seen before, but have been told by 1 gunsmith that it could be a factory finish. All the info is below. If anyone has any info, I would be greatly appreciative.

Serial # 150XXX (The full serial is visible on the watertable)
1909 manufacture date based on the serial #
Side by Side Double Barrel 12 Gauge
Rib says Vulcan Steel
Lines on the rib go all the way to the end of the 26" barrels
Blueing faded on the barrels
Barrels need to be tightened (have a little play in them)
Case has tiger striped symmetrical pattern
Frame size on barrel lug is faded

I am curious about the following info:
Did the shotgun actually came with the 26" from the factory?
Does the case appear to be factory finished?
Any idea of value?
Is there anything in the order books on the factory frame size?
Any other info on the gun from the experts here that I am not bright enough to ask about?

I have new, but from what I have seen on the forums, the Research Letter is important to have, but it doesn't answer some questions and even raises other questions. I plan on getting the Research Letter, but I was hoping to get some informatino beforehand.
