Rt. 50, in Fairfax City, about 15 miles out from downtown DC, south side of the road there is a little hat/boot store. They will most likely have it and about the number your are looking for.
I am confident you will not find a website for them as it was run by a 240 year old H&W, (each, not combined) who laughed at me when I suggested website.
I do not recall the name but I strong suspect they are still there and not real tough to find if you drive the area.
