Yo Trooper, that's one big lot of boxes you are looking for. I am always on the lookout for different boxes for loose sets I have bought. I did thread about this sometime back. I tried a couple of the Toy makers and they wouldn't sell me their boxes for their sets I had, which really miffed me off couldn't understand why they wouldn't sell them, after all they are all struggling to sell items in the market and $$$ are $$$ so they don't want money. I said then there is a big opportunity for someone to start doing Re-pro boxes, either with tie cards in or foam. They don't have to be made specifically for one set IE: you could make them for a set of five cavalry or boxes for infantry, don't need labels on them you can do your own labels. If you look in my album on boxed sets you can see some of the labels I made for the sets Jeff painted of Old Britains. I lot of makers today just put stickers on don't bother with fancy labels, there is nothing fancy about Frontline labels. I think they would be easy to copy if you could get a box near enough to the colour and cut you own foam to suit your sets. Anyway Cobber will keep my eye open for you and let you know if I see any going, the live auctions are sometimes a good bet for items like this.
Bernard.
