P&S Steamer Trunk

This trunk was given to my mom from my great aunt. It has been stored for awhile now and the house is being sold. We need to do something with it. I've done some research to see what I can sell it for but something puzzles me. Everything I've read about P&S has a yellow label. Why is mine red? Both handles are intact and when I was little I used to play with the old lock and pretend a magic potion would come out of it. Unfortunately the lock is now missing. Also what year do you think this is from?
Thanks
