The FBA may very well be for Fulfilled by Amazon. Having worked with US Luggage before, their model numbers are pretty nice and meaningful. They’d have a dash as a seperator before a color code, but never an underscore!
The actual model number for the Solo New York Bradford Collection Mercer Briefcase is SLEXE3359.
Have I mentioned lately that I sell bags and bag accessories?
I will say that I haven’t held a piece from the Bradford collection in my hands, but I have seen some of their other collections in person. We don’t carry Solo anymore, but do carry US Luggage’s higher end brand, Briggs & Riley. Still get the catalogs though.
Since they’ve updated the collections for Solo, they’re much nicer and for $25, I’d have a hard time not recommending it.
