How do I determine which set number from a poly bag I have a poly bag. It is number two in a set. Underneath the number is 342R7. The set is from 2015. The primary colors are burnt red, yellow, and gray.
This bag is from 60150-1: Pizza Van

Based on:

6015347: Plate 3X3 in Medium Stone Grey
4618986: Plate 2X6 in New Dark Red
And the yellow parts

According the instructions bag two is for the van
