Hinges - part No of the hinge ?

Hinges 27 years old - came on cupboards from Selba


I have laid out thee of the hinges (from opposing doors).

The one on the right clearly says Hettige.
The left and center one are both different from the hettich marked one, and each other. They have similar marked and numbers from the stamping process but are not exactly the same.

The one on the left has a W Germany in the stamp where there is a blank on the centre one.

The sliders for all three hinges appear to have identical stamping.

The cup depth on the one marked hettich is close to 11mm while the cup depth on the others is about 12.3mm.

The physical length of the slider that mounts in the cabinet is 1.6"


Question What is a current / compatible Hettich hinge to the one on the left.
