Mono blocking and sleeving are two terms that basically mean the same thing when referring to repairing a Parker's barrel assembly. When a Parker's barrels are damaged beyond safe use, a competent smith can cut those barrels off in front of the chambers. The chamber part is called the monoblock. The smith would then ream out the chambers enough to receive new barrels, complete with new chambers--sleeving. The new barrels are inserted into the monoblock and permanently affixed with silver solder. After dressing off the outside joint where the barrels meet the monoblock, the ribs are attached and the barrels finished. Assuming the job was done by a competent smith, the barrels are safe. Many cheaper Italian and Turkish double are built originally with monoblocks. You can tell this by the visible line or engraved line on the barrels just in front of the chambers.
