These are resin printed to order and you will receive 4 ladders and an additional 2 as spares as they are fragile. You will need to glue these to your wagon taking note of the orientation with the image.
 
This is a black resin but does appear slightly translucent grey due to how small these items are. Please refer to the image for this visual. Some additional re-work such as painting and removal of any surface imperfections may be required for that perfect look. 

Wagon in the image is not included in the sale.
 
Any questions please ask, if you have additional requirements please message me as I do design all my own parts and more.
