Just a thought prompted by the photos. It looks as if the original main entrance to the Four Oaks (no1) was actually off Tudor Road, this might explain some of the puzzlement over the number of doorways off the Parade into the terrace. Simlarly, the entrance for Sefton Gate at the other end of the block was off Abergavenny Road, when it became the Cae Mor, the entrance of the adjacent property off the Parade was used instead. I think the owners have now reverted to using the original one -now off the car park - as well.
