Due to the Danish import regulations, it is immensely cheaper if I could source some hardware from Europe.
I managed to find some chest locks from Rutlands in England, that were reasonably priced.
They also carried brass corners, but those were kind of expensive.
A good friend of mine once suggested Toplicht as a possible source for some specialty hinges.
I sent for their catalogue, and I have also browsed their web page. The result: They really do stock most of what you could imagine.
I ordered the following items:
Brass corners at a price of just below 6 Euro a piece it is a stark contrast to the prices demanded elsewhere. The corners are cast brass with a thickness of approx 1/16". If you order more than 5 there is a discount.
Brass drawer pulls These look very much like the later type pulls shown on page 10 in "Campaign furniture". They seem to be a little bit thicker than 1/16. These are only 9.90 Euro a piece, if you order a single piece. Like the corners, these pulls also come with a discount if you order more than five.
Brass hinges These hinges are 5/64" thick and seem to be of a good quality. They are 13.90 Euro a piece, so they are a lot more expensive than the usual hinges I buy at the lumber yard, but the quality level is also quite different.
To get a discount on the hinges, you will have to buy at least ten.
The shop was really fast, I ordered the stuff Friday and I got it today. All the items were wrapped in newspaper for protection. Not that it matters much with brass hardware, but it gives a fine impression of the store, that they make sure everything is securely wrapped.
I ordered the locks Friday as well, but those haven't arrived yet, so therefore there is no review on those.
So if you need campaign hardware, I recommend Toplicht.de as a supplier. They have loads of interesting pulls and specialty hinges etc. and the prices seem very reasonable, actually downright cheap for some of the items (please note that I am in no way connected or affiliated with Toplicht).
