Usually it means orient the long groove to the left and thread it left to right.
Years ago I had a German machine that looked a lot like yours. I don't remember the name, but it took 16X231 needles. The 16X231 is AKA DBX1, a very common industrial needle.

That makes a lot of sense, thanks I will try it. Does it matter whether it's a flat shank or round shank if both fit? I am being lazy because I have so many packets of needles to try at him already and I haven't been out to purchase anything specific yet.
