Welcome to the Forum!
A 2-digit gun like that is very desirable. However,, it's condition does hurt the value.
The turn line on the cylinder, the worn spots on the front of the cylinder, the ejector rod housing worn, (yes,, that could be replaced,) the left & right side muzzle wear, the edges of the rear sight wear, and the medallions in the grips missing paint,, all point to a gun that's not in excellent or even very good condition.
Yes,, collectors are picky! :oops: :rolleyes:
The gun's barrel should be measured as from the face of the cylinder to the end of the muzzle. The only factory issued ones had either a 4-5/8" or a 7-1/2" barrel.
The ERH, and the grips can be replaced with better ones. But the turn line, and the bluing loss at the points I can see are not easily corrected. If you had the gun re-blued,, it would hurt the collector value. But it's condition also hurts it. But most collectors wish it to have the original finish over a re-blue, even if it's got wear.
The RENE price guide puts the value of a normal .45 OM like that in excellent condition at about $850. A 2-digit gun like that IN EXCELLENT CONDITION is listed at about $2500.
Sadly,, that gun will not pass the excellent condition grading to a collector.
I'd offer a guess of value to a collector,, who wanted that 2-digit gun,, at around $1800-$2000 maybe. A collector would want to CLOSELY look the gun over to assure other issues are not present.
As we collectors say; "The devil is in the details.!" And it's especially true when you are looking at a serious purchase.
