Yes,I had very high confidence in the manufacturer. Unfortunately, all the Facet S/N samples I've managed to collect so far, all start with 'YF6'. I'm trying to determine if the 'F' is a month code, fortnight code, year code or something else. With both an 'F' and '6", I'm not sure which is the year code. Unfortunately I can't access the photo link you kindly submitted but based on my personal research it looks like they manufactured aluminum frames for several other recognizable brand in the late 1980s. Now I know they also had an eponymous brand, Thank-you.
