HO Scale 16 chick crates

These are a model of the crates used to ship baby chicks. 
They are based on measurements and a photo a fellow modeller obtained of boxes used back in the 40s.  They are cardboard and should have a bunch of circular holes in them that are not modelled in this part.  The modeller will have to add black dots when painting the crates.   
They have no bottom, and the sprue goes up inside.  It can be easily snipped with sprue nippers.  Rince them in mildy warm soapy water to clean off the residue before painting. Good luck!
