Search for instructions IKEA hinge corner cabinet old series late 90s

Hello, I urgently need a photo or assembly aid of the old hinge for the 90s carousel cabinet from the Faktum kitchen. The cabinet was purchased in the 90s. My cabinet doors were dismantled during renovation, presumably parts (screws of the adjustment mechanism) are missing, new current door hinges for the flap door do not fit the old cup holes. The dismantler has meanwhile passed away and took his secret with him, who has a picture of the old hinge (the one in the middle that connects both doors at a 90-degree angle) or the old assembly instructions. Unfortunately, I can't manage it logically. Thanks heideline

Hello,
if no one here still knows the hinge, photos of the hinge and the doors with the drillings and possibly the manufacturer name would be helpful.

Isn't it the same as today???
