What have you done today with your Austin Seven
The Barlow sump is the same as the semi-deep sumps that we now manufacture. The semi-deep is favoured (particularly by those racing) as its design holds about the same amount of oil as the standard, but it is deeper at the oil pick up. This semi deep finned alloy sump can be removed along with the engine, whereas the deep type needs the sump to be removed first before taking out the engine. Holding the same amount of oil means it can heat up quickly enough and also can be cooled by the finned aluminium construction. It also helps stiffen the crankcase due to its solid construction and in built stiffeners, also less prone to leaking than the flimsy pressed steel type.
