Goose/Geese book question

Goose Question, I have the book "Colorado Rail Annual #9" with one chapter devoted to the Geese and it mentions that only 3 photo's were ever found of RGS goose #1 and shows the photo's.

I also have the book "Rocky Mountain Railroads, the RGS 1 by Dorman" and on page 46 it shows a picture of RGS goose #1 with what looks like a wood extended cab with window that seats 4 and a square covered cargo box. Is this the same #1 or were there two #1's

Also is the book "Galloping Geese on the Rio Grande Southern: Tin Feathers and Gasoline Fumes" cover more RGS geese than the CO Rail Annual #9???

Thank you,
