I thought (and could be mistaken) that the 11D had a 5 bearing crank and from your pictures, yours is only a 3 bearing Perfo block
The original Perfo Crank has an oil trower on the crank where yours has the knurled section so looks like Citroen did change the oil thrower type on late TA engines to that of the upcoming D series cars
Just goes to show that not everything you read is correct with a Traction and it needs someone with specialist knowledge to explain this one properly
