1/18 Scale Car Engine Radiators- 8 pieces and 1 set of Ramps

Description

I believe that these are 1/18 scale. I am unsure. They could be 1/24 or 1/16. Please look at all of the photos to determine size.
Please look at all of the photos because I do not accept returns.
I purchased these for my son’s diorama and he did not use them.
These are all plastic.
This is a set of ramps that he did not use, either. The ramps are of unknown scale, too.
Please contact me with any questions and I will gladly answer.
