Check out "CUSTOM GUNCASES AND ACCESSORIES", they are from Australia. I have been in contact with this guy and he is very open to doing custom items like "Maker's" names on snap caps and oil bottles.
He sells a line of cases as well. Not sure if they are finished on the inside but that would not be a problem for someone here in the U.S..
My friend purchased two "Boss" oil bottles from him a few months ago and there was no problem with getting them and the oil bottles looked great.
Check him out, he seems like a really nice guy trying to get into the business.
