Any idea how old this machine is??? It's all metal body and inside it's mostly metal except the the worm gear and cam gear (not sure if this is right name for the part). I haven't had a chance to open the bottom to oil it and gears it yet so maybe there is more plastic below.
I have done a search trying to find out the year this machine was made and so far came up with nothing for a date/year. I believe it was made by Janome for Sears but not 100% sure on that either. It's super clean insid and out and doesn't look like it been used much except for breaking a few needles (needle was bent and point missing) on the face plate but I see I can still order a replacement from Sears. So far it seems to sew great doing a straight stitch but since I haven't pulled off the bottom to finsh oiling I only ran it a few inches on fabric. Well here is a picture of it before I started to oil and gease the top part and bobbin area.
