I have an old full frame pie cut corner cabinet with bi-fold doors. The hinges holding the doors to the frame broke at the tips where they mate with the base plates. The base plates are still good.
There are three fuzzy images of the hinge included ? side, bottom and tip. On the part that is attached to the door (right end in image) the hinge is numbered 666.265 61.00, made in Austria. On the arm in the middle of the image is 624.310 11.00. On the tip piece (left end of side and top images) is 591.290 00/00. The lighter color circle on the tip piece is the screw that holds it to the arm. The tip piece broke. The left end was originally longer with a hole where the set screw on the baseplate holds the tip piece in place.
The part that goes on the frame is numbered 346.290 51.87, made in W Germany. In the image bracket in frame ? side you can see the set screw and the broken-off tip of the hinge. The distance between the screws going into the frame is 1 7/8 inch. The cabinet frame image shows one bracket in place and the half-round cut where a bracket has been removed. The half-round cut is ¾ inch deep and 1 3/8 inch high.
The door overlay is 1 1/8 inch. The cabinet is 42 inches high and has 3 hinges.
