This is from a gun collection, part of an estate with which I am helping a friend.  Basically, I am trying to establish a fair market value for each item.  That whole story is in another thread, if you are interested:

Older firearms are not my best area, but there is plenty of information on this particular model in the Blue Book, etc.  This revolver is decribed by the owner's family as:

Colt, Single Action Army .45, Standard Model (1955 - 1982) Serial # 23XXX

My most current copy of the Blue Book indicates that this revolver was manufactured in 1958 and refers to it as "Early 2nd Generation."  It places the value at $2,150 for 100%, $1,500 for 95%, $1,200 for 90%, etc.  As you can see from the pictures below, the Colt is in excellent condition for a 45-year-old gun.  It only has one blemish (a spot near the end if the barrel on the right side - see last picture), slight wear overall, and it has no box or papers.  I suspect that it would rate on the high end of the percentage scale despite the blemish, but I am no good at assessing those percentages.  I would appreciate any advice on how to evaluate/price this firearm fairly.  I would prefer to avoid the hassle and expense of having these firearms professionally appraised, but I would like to be in the right ballpark when I establish the value.

Right now I am thinking $1,200 for this Colt - does that seem fair?
