Here are my trucks and whistles.  The two columns from the left are R1 and R2 trucks.  The two columns from the right are R4 and R3 trucks.  The center column and top row contain the very rare monochrome trucks and the party favor trucks.  Across the top are the whistles, with the (also very rare) mono whistles in the center.

I bought the display rack in late 1999 and put it in the closet "until I have time".  After three years it is finally on the wall. Too bad the verticals warped. :(

This next picture is a supposedly limited edition Nivea truck from Austria and an R1 mono.  See how the color has changed?

Trucks and whistles are fun.
