These are the files to print up the Supermarine Walrus some have seen on my HMS Queen Elizabeth. I usually print most the pieces in the same "silver" (grey) ABS used for superstructure, except for the prop and engine radials (which I print in black).
There is a complete assembly tutorial under "Additional Information" ("https://www.greywolfsquadron.com/supermarinewalrus.shtml")
