I used to work for Drexel Heritage. I don't think they made WL's bunkbeds, but they did the Swan and Dolphin initially, and also the hotels at DLP, as well as others. We sent employees to Paris when the furniture was delivered so they could do any repairs needed from shipping the furniture. Talk about country-come-to-town!!! Our crowning moment was doing the furniture for the Venetian in Las Vegas.
Here's how to see who made the furniture. There is a tag under a cushion in the upholstered items. And in a drawer there will be a name plate somewhere. If that fails, it is ALWAYS stenciled on the backside of the furniture with the company name, design number, and plant number.
