Here is a auction on ebay:

1973 Opel Opel GT 4 spd original Daily Driver HD Video! | eBay

It is original and a survivor in really good shape. The interior is survivor quality but presentable. The dash looks good and the headliner is good. The seats are in good shape. The gauges are working and speedo/tac are working.The manual rotating headlights work easily.

I wonder if the engine is original or not

There are some late 73's with this valve cover. As the plant ran out of GT specific parts they used Manta parts much like the change to the rear tail lights on the 73. I have had 2 GT engines with this valve cover, both were 73's, I recently sold one of these valve covers to a lady in Florida that wanted to keep hers OE.

Wow that is pretty cool info. I never knew that.
