In between K-Line and O-Line Reproductions, there was RMT (Ready Made Trains). To my knowledge, all RMT packaging was replaced with packaging labeled "O-Line Reproductions," but the products are the same. I bought some RMT switches a few years ago, had to return them, and the replacements came to me in O-Line Reproductions boxes.
The O-31 switches are still somewhat readily available on ebay, but the supply of O-72 switches is dwindling. They are fantastic switches, and I'd love to see someone start producing them again.
