Attached is an image of a 10x15 plate holder that is a little too wide to fit my Goertz Tenax Taro. Here are the dimensions that I have measured to the best my eyesight can provide:

111mm wide x 180 mm long, 2 mm edge and 3 mm lip at the top. Dark slide has Made in Germany stamped into the top of the dark slide.

Any assistance in identifying which camera or line of cameras this fits and what type of plate holder, size wise, would fit my Tenax Taro?

Thanks in advance,
