As I was completing work on my 1:48 Gato boat, I began a search for some US Navy style numbers for the conning tower and bow. After some searching, I discovered Jim Botaitis who had some numbers for battleships. I emailed Jimbo and after a series of emails, he has developed some Gato submarine decals that are absolutely great, and could be used for US subs and other US Navy vessels. His website is http://www.jbot.ca. He has enthusiastically worked with me to produce the decals, and I think you will find them most useful in providing the finishing touch for models in several scales.
