Barrel lever a bit to the left
 

Was on a different forum and this was mentioned on a way to get it back to the right. https://www.youtube.com/watch?v=YXbrmmiSngw . Some may not agree with the method, but I went out to the shop and did one of my SxS's - it worked great.

Lever position on a Parker means little. All that matters is if the gun is tight or not.

Other guns might be a bit of a different story. But same holds true when it boils down to it, is the gun tight or not.

the fellow sure tightened up that old gun..now if i can do half as good as him i ll be a pro in my mind...good show... charlie

It is nice to have some theories confirmed by an old British gunsmith. I have fixed a few guns with welding. It has been my experience that most guns "off face" have this problem, however I recently worked on an l.c. smith that locked down tight, most likely from the rotary bolt, but was very off face.

In my limited experience, when I have a gun with the lever off to the left the gun has been loose and off face. Once properly repaired the lever sits just fine.
That was a good video and I am not criticizing but I think it could lead to someone following that process and figuring the gun is now nice and tight and it may not be where it counts. Just a thought.

Watch their other video on rejoining barrels. That completes the story. I suppose knowing when or when not to do either process is the experience part. All the same some really informative videos Mr. Potterfield has put out there.

I have used the tighten the bite procedure on a couple of my guns and it worked well.
