Thanks for the info so far. I was also able to get a bit more info. I found out that this one was made in 1907 ( serial # in the 73,000's) and has a "perch belly" stock, half moon butt plate, checkering and a marbel tang site. However, the number on the foreend was too faint to see if it matches the gun. The lock on the barrel is tight, with no movement. However the lever is a bit loose after the gun is cocked, it has about a half inch of play up and down (a bad spring?). The lever is also blued and not case hardened, which leads me to believe that the gun was redone at some point. In addition, the bore condition on closer examination is a bit worn, but no pitting.
With that being said I wonder if I should move on and look for another one? Or is this one worth the $499.00 asking price?
