Smythson of Bond Street, based in England. Is that obscure enough? They are an upscale stationery maker and ventured out to bags in recent years. They have amazing sales and I often score great bargains for amazing bags and SLG.
I've been eyeing Smythson for quite some time, and just bought my first Smythson notebook a couple days ago. Your bag looks gorgeous!
My "obscure" brand is Valextra. No logo and most people can't identify it at a glance. I have their bags, wallets, writing folders, etc...
I have a Valextra wallet! I love the quality. It has a really nice smooth leather lining.
My favorite obscure brand is Loro Piana. Quality leather and very durable. I'm not sure how well known they are, but I haven't seen too many posts on TPF about them.
