I think Steves part nos are for a later type GB1057 as the hinges are handed.
The part nos for 195 303 852 GB1057 73 LHCS are
Left Hand hinge 109222
Right Hand hinge 082830
To remove the door on this type you turn a lever mounted in centre bottom of inner door not in the hinge.
Normally its just the spring part no 023857 that breaks on these

yes it was the ones you said clayside
the left hand hinge has snapped
unfortunatly they phoned to say the grandson had fixed it
pesky kids
as it was snapped i presume they have ordered another one
