Thanks, folks.
The overall height (heighth?
) is 10 inches (25.4 cm (25,4)) and the length from tail to tip of tusks is around 4-3/4 inches (12 cm) give or take a few microns.
As stated before the high resolution picture was saved and printed onto one sheet of USLtr size cardstock. It looked to be too small so the picture was enlarged and printed onto one sheet of 11 x 17 cardstock for the build. Then I figured the enlarged picture could be separated into two USLtr pages. The single enlarged picture can also be printed onto one A3 size cardstock sheet and the separated pages can also be printed onto two A4 size cardstock sheets.
The original picture that was saved was cleaned up a bit to eliminate as much of the brownish discoloration without seriously altering the vintage look of the model. The color balance, saturation, and contrast can be manipulated to get the look you want and also to help preserve the vintage look.
