Vetus WLOCKLR 45mm. Slightly shorter but otherwise straight in as there is enough slack in the aft hose to pull it forward. Worth considering having the end plate welded. I had mine done cost about £50 and better than new. It is only the underside of the outlet pipe that corrodes at the weld and creeps down the end cap and the guy who did mine welded up the pipe and put a plate over the lower part of the cap.
