I am trying to restore some 50 year old photos (b&w) and I scanned a large photo in two scans. Everything is fine except for the line that is apparent not matter what I've tried (clone tool,healing brush etc).

TIA

Hi Art! What's happenng is that you're scanning one picture in two scans, but you're trying to matchup a seam that was exposed to different sides of the scanner's lamp.
A scanner's lamp doesn't have uniform brightness across it's length, so that the left side of the lamp is not the same brightness as the right side. When you do a two part scan, you place the photo on the scanner so that one side (let's say the left side) of the picture is resting on the scanner's glass, with the right side of the photo hanging over the right side of the scanner. When you make this scan, the left side of the photo will be scanned with the left side of the lamp, and the middle of the picture will be scanned with the right side of the lamp.
Now when you try to scan the part of the photo that was hanging over the right side of the scanner, most people just move the picture over so that the right side of the picture is now on the scanner's glass, and the left side of the photo is hanging over the left side of the scanner. When you make this scan, the middle of the picture will be scanned by the left side of the scanner's lamp. In the first scan, the middle of the picture was scanned by the right side of the lamp, and in the second scan, the middle of the picture was scanned by the left side of the lamp.
Trying to matchup the two sides that were exposed to different lamp brightnesses will cause the problem that you have. The way to prevent this is to turn the photo around 180 degrees when you do the second scan.
Since you already have the scan, you just need to select one side of the photo at the middle seam, and adjust the brightness/contrast, then use the clone tool and healing brush to remove the seam. Here's what it looks like:
