Not jilted or remorseful at all. I've owned two sleevers, both Brit, and both PROPERLY MARKED as sleeved. Falls in the same category as any other significant modification to the gun. You lengthen chambers, then stamp the @#$%^% gun that it's now 2 3/4" vs 2 1/2", or 3" vs 2 3/4". Why are people afraid to tell the truth? Shotguns, if properly cared for, will outlive their current owners. Somewhere down the line, the next owner may be less scrupulous, or the next buyer less knowledgeable and less likely to spot a sleeved gun. You're mixing two threads here, but no need to submit it to anyone under our current system in this country. Appropriately marking whatever modification was made means that there's no misunderstanding about what's been done to the gun.
