Assuming you are looking for HO scale, the Walthers 2006 HO scale catalog lists builder's plates decals as a new product available from Microscale, catalog number 460-4309. Go to the Walthers web site and search on this catalog number for pricing and availability. I just now performed a search and these decals are not available from Walthers. They don't have a projected availability date, so you'll just have to keep looking every month or so. http://www.walthers.com
