Re Mansell St
Bring up Orinoco's map and go to C2.
Go up Upper Brook St crossing over Grosvenor St, turn right into Mount St, you will come to a bend in the road.
Mansell Street is between the bend in the road and just above Bedlow St.
Mansell St is not showing on Orinoco's map, just a empty area, but it is on my 1960is A to Z.
