Thanks, Pete, for mentioning Customer Service Hardware (CSH). I should have referenced them as well. They have an extensive selection and truly great prices. They are wonderful folks to deal with, just as Lee Valley. Both are very, very service oriented, and they treat their customers well. I have never had a problem with either, and have ordered thousands of dollars worth of stuff from them.
One more company that meets the customer service standard, and has beautifully crafted, American made hardware is Horton Brasses. They don't have the type of stuff that Steve needs, but it you are looking for high quality, solid brass hardware, they are high on the list with very personal service.
The usual disclaimer: I have no association with any of the above noted companies other than as a very satisfied customer.
