Gotscha works mainly with historical war objects such as weapons and harnesses. He is in great demand as a restorer. "My first major commission in the Netherlands was to make a replica of the harness of prince Maurice, by order of the Dutch Army Museum. A difficult job, because everything had to be entirely historically accurate. Fortunately the Dutch Army Museum was very satisfied." Gotscha’s success did not go unnoticed in Georgia. The National Museum was very eager to work with him.
In the museum Gotscha led several workshops for a group of young restorers. Jointly they restored eleven top pieces from the collection of the museum. Gotscha: "The most important piece was a sabre of Erekle II. That is the most famous king that Georgia ever had. The end of the scabbard had been distorted, as a result of which the sabre did not fit in it anymore. Now it looks exactly the way it did in Erekle's time again."
Gotscha looks back on a very successful project. "When I left for the Netherlands in 1995, I was the only restorer of weapons in Georgia. Now many people work in the National Museum." They learned a lot from Gotscha, as shown by the many positive reactions that he received. There were also favourable articles about his work in the newspapers. He remains modest himself: "I am not necessarily better, I just have more experience. The projects of IOM are aimed at transferring that experience. I am glad that I can do something for Georgia in this way."
