I am not sure this would classify as a vintage serger but it is very hard to find any info on it. I am pretty sure I bought this new in the 90s.
Bernette made 335D and 335DS which are each two tone cream/brownish. My Bernette is all creamish.
Recently I have relocated my Bernette 335S Serger nicely stored in its carrier case W/O its power cord & pedal. Ugh! I believe it was manufactured in in the 90s but cannot find any info on that specific model.
Here are some photos of it.
PS: sorry for the dark photo
