In Australia and in much of the rest of the world rear bowl 6 bolt crank sumps from Escorts are still cheap though some of the special versions are more expensive. Front bowl 6 bolt crank sumps from Cortinas are expensive as they have all disappeared into Elan owners spares cupboards ( including mine which I include in my retirement calculations ) or been used to convert 4 bolt crank engines to six bolt crank to stop oil leaks.
Ford had a couple at least of slightly different patterns for the 6 bolt crank front bowl sumps as well as the difference between the 4 and six bolt crank versions. Lotus used what ever they could get from Ford that suited.
I would not worry about the shape of the front bowl as they all work to the same poor degree on the 6 bolt crank engine with the RH side pickup unless you do the needed proper pick up mods and baffling to stop loosing oil pressure on RH corners.
