Concreted in toilets are a nightmare

This video covers the salvage of 2 vintage toilets from a building that is going to be demolished. The base of each is set in mortar, and the first one has suffered damage from a recent 5.9 magnitude , 9km deep earthquake in the area. The second had an old crack in the base. Toilet 1 is a 1965 Shanks Nisa MFG date 23/3/65, toilet 2 is a Armitage Ware Magnia from around 1951, I cannot find a date on it. The matching Armitage Ware basin is dated 14 Mar 1951.
