Original with working buttons and flip up trigger. These were mostly used in the Messerschmitt BF109.
I have got some questions about the painted markings. The letters and number are references to manuals and electric diagrams. I have copies of several manuals with electric diagrams where they are visible.
I think these where made at the time of field modifications or perhaps when the aircraft was taken from the front. In my opinion they are original from the period.The item "Ww2 German Luftwaffe control stick KG13A" is in sale since Friday, January 22, 2021.
