We have this sewing machine, Deluxe Zig Zag (not Singer or Universal, made in Japan) Model 6100, that we have been unable to track down any info on. Really need the manual for servicing, adjusting tension etc and cant find the model number or any Deluxe manufacturer info. Don’t even know if they are still in business or were bought by another company or ???? 

Are any of you familiar with this machine (photo) and do you know of any resources we might contact for a manual? Any help is appreicated. I have been all over the internet, entered all the keywords I can to search and come up with nothing usable.

Thanks. MaNaHo
