According to the list at
http://www.doubleveil.net/zssmp/resources.htm#jajc your machine was probably made by Koyo.
I can't tell for sure, but it is possible that you may have what is considered a left homing machine. That means that if machine is set for straight stitches then the needle will stitch only on the left side of the oval of the zigzag foot. That is a nice looking machine. You should be able to remove the top and nose to oil the machine where metal meets metal. Try not to get any oil on the plastic gears or cams if it has any. Also oil where metal meets metal on the bottom of the machine, too.
Have fun with you new machine.
