I just completed a model of IJN Tonan MAru #3, which was built by Japanese yards to a design from Norway and the united Kingdom, completed in 1938. The design was that of a whaling factory ship, converted to a "multi-use transport". Here is a photo. More photos can be found on my website, "miniaturemodeling.com" , in the Japan WW2 Other Types gallery. I don't know if this particular ship has ever been modeled in our 1250 scale. Anyway, here she is.
