I just picked up this Tecmic and am having a hard time finding any information about it. The guy I bought it from didn't know much. Is anybody familiar with the brand or model? Is it a Juki, Pfaff, Brother, clone? It seems like a solid machine, but I'd love to find a manual or even info on needles, bobbins, oiling, threading, accessories, etc? I'm also very curious about the gauge on the front. Is it for measuring a backstitch? Any info would be greatly appreciated
