Vintage Michael Scott English bridle retailer leather briefcase/attaché/ business/ computer/travel bag/messenger bag

Not sure of its age. I'm guessing the seventies era. In spite of exterior marks on its thick leather it has a lot retailer of years of use left in it. Tons of character! See photos for measurements and condition. Leather strap shows very little wear and handles are solid. Some marks show interiorly. Zipper in nice condition also. This is a quality bag as evidenced by its years of use and continues to be very usable and has a charm all its own!!
