Need help with identify a 1935 Chevy Fire Truck

[Jim_1937_Buick]

I am helping out a group working on a 1935 Chevy Fire Truck.

I was wondering if someone might help me identify what we are working on.

It is a 6 Cylinder Block number K53231-0
How can I identify what size engine is this? (It is possible that it is not a 1935.)

I would also like to know how I can identify what size truck this actually is.

Thank you for your help

Not sure you have the right number. I can't match this to the numbers shown in this link, but maybe it will help.
