I recently bought an antique sword from Lambert & Lambert Antiques, and have been delighted with every part of the process.
The sword was listed with plenty of information and plenty of images, so I knew what I was enquiring about; one of the proprietors responded to my enquiry swiftly and in a friendly fashion; the invoice was issued within a couple of days and payment was not a hassle. The sword was dispatched within a week, complete with tracking number and a very reasonable cost for postage.
Upon arrival, the sword was packaged exceptionally well, both for delivery and for storage once it reached its destination. Not only was the sword packaged well, it came with care instructions for maintenance, and also with a little booklet giving a very reasonable amount of information about the type of sword in general, and about this specific sword in particular, complete with suggestions for other literature to read for further information should I be interested in researching further.
This is truly one of the best companies I have ever dealt with, in terms of their attention to detail and going to great lengths on behalf, unrequested, above and beyond the simple sale of an item.
