My 29-18 showed up about a week ago. Surprisingly it had a manual/parts catalog, and a nice, detailed exploded schematics. The only other machine that had a better user manual than this was my Thompson mini walker. Before it arrived I had been searching for anything that had to do with the cobra specifically. I found a whopping minute and a half if watched on slo-mo video dealing with threading the machine. If you were a first time buyer, the manual included would be a better help in getting started than nothing, but If a person had never used a machine before i can see a mental breakdown and a patcher thrown out a window. It did have a bobbin winder and I happy to say, it’s very functional and seems to work better than the afterthought winders on most stitcher. I give the entire purchase from start to finish 5 stars and a heck yeah.
