Assuming you have the correct chaincases for 1936, with the round cush drive cover rather than the pear shaped one, you will find that the clutch cover you need is one for a Square Four, 1937 onwards, but fitted upside-down! Sadly, this means you need to weld up the hole which will be at the top, and drill another at the bottom. This wrecks the chrome, so what you really need is a useable Sq 4 cover which needs re-plating anyway.
