I was given a Japanese 4-6-4 in a box with no tender. It is a heavy metal unit with some plastic that doesn't currently work. It has numbers on the bottom (KS 21070) and Japan under it. The front has a round blue medallion with japanese markings and a white bird on it with the word - TSUBAME - on it. The drivers appear to be N.S. and in good shape. The box has a number - SL C-62 on it. Can anyone point me in a direction to find out all I can about the loco. I can e-mail you about 6 good images if you can help. Thanks.
