I suspect the tube was cut by PO to feed snake in both directions when the old cable broke. Many Bristol k/cb have had this infamous tube modified or relocated. I cannot tell you if, on the 32, the tube needs to be attached to the engine mount. It does need to be held in place to something (usually glassed in). I can tell you that Bristol owners are quick to replace that cable when it shows wear because it is a pain when it fails on you. Can't snake the tube due to sharp angles.
