I have been coming to this site for years looking up hallmarks and wanted to say thanks. I have a Durham sterling silver creamer and sugar set from the 1947 United Van Lines Convention in St. Louis. I noticed there is not much information on the this brand. The hallmark list on this website says this company was around c. 1950's-60's with only two hallmarks. The plate is hallmarked with Sterling and Durham. The creamer and sugar bowls are marked Sterling with a hallmark not pictured on this website. The bowls, I guess, could be from a different manufacturer, but the set is all engraved the same.
Well, I am attaching some photos of what I have and if anyone wants to use this information to update the hallmark list, go for it.
