This is an Illinois Terminal combine kit, part 2 of 4. This part of the kit includes the right side of the carbody.
Wash all parts with simple green and an electric tooth brush, then scrub again with hot water, prior to assembly and paint.
The parts of this kit have interlocking pegs to ensure correct placement before gluing. I reccomend fitting the part, then using a toothpick or similar to dab ACC (super glue) on the seams between parts. Be careful with the small locating pegs on the pilot and at the corners of the front end, they will break very easily and are only meant to ensure alignment before applying glue.
Before you ask, this kit is sold in four parts because I'm unable to combine them into one file without crashing my program. They are that well detailed!
