Flues guns are NOT equipt with a rotory bolt. Only the later NID is fitted with that type of bolting.
The Flues is hook bolted through the rib extention.
That set of barrels is extremely off face. A very large shim will be required to set the barrels back against the frame. Or a good deal of welding and refitting.
The barrels are also very proud against the frame. Might be best to bail on this endeavor.
