I'm not even sure this is a vintage machine, but I cannot find anything about it on the Baby Lock website. It says Baby Lock Companion BL500 on the front. It was dirty and needed a new belt...I replaced the belt, cleaned it up inside and out, oiled it and plugged it in. She purrs like a kitten and is fast and quiet! She is small like a featherweight and really cleaned up pretty! I absolutely love this little machine and would like to know more about it. Any ideas of where to find info? serial number is: sz900830544 Thanks for whatever help you can provide!
