What is the difference in vaseline and singer grease?
Oh boy!!!!! You need to take several photos of the machine and post it!!! From what I can tell from the bottom and the serial it was made by Koyo-Seiko. This is the first Japanese 99 I have seen and with it having an "SK" on the faceplate helps me with the manufacturer along with the serial.
I did add this thread to the Virtual section for Vintage Machines because this is a very important machine! Especially for my Japanese research I am conducting.
Thank you for posting the photos and I am looking forward to seeing more of the machine!!!
