This looks like a great kit. There are complete sprue and decal shots over on Cybermodeler:

Those two kits are of the S55X, which was a larger, somewhat different aircraft. The S55 came first, was smaller, sported open cockpits, different engines, and had a smaller payload. An example of the S55 and one the subjects of this kit still exists in the Sao Paulo Brazil aviation museum:
