Regis,
Thanks for your response. . .I checked the link to Ohio Travel Bag. . .and I thank you lots, cause I've not found anyone with quite that diverse of inventory. They will be a big help for future orders for sure!
I think my description of what I was needing was not real accurate. I actually need the entire rectangular metal frame for the briefcase opening, as on the attached picture. In most of this type of briefcase, it is just like 2 pieces of thin flat-bar metal, bent and bradded together to make a hinge. I've assumed that someone sells these frames separately, rather than everyone making there own.
Still Looking. . . Thanks
