The first Chevrolet "truck" was a 1918 ton truck.
The vehicle in the picture looks like a "Light Delivery" model to me. The frame is shorter.
Cars and trucks can use the same design tag. The ID tag that says "Four-Ninety" was used from 1916 to 1922.
The tag in the picture looks like those made from 1923 to 1932. Unfortunately the model name is not readable in the picture.
1923-26 Superior models (B, B&F, F, K and V)
1927 Capitol model
1928 National model
1929 International model
1930 Universal model
1931 Independence model
1932 Confederate model
After 1932 the tags are a different design
I shamelessly robbed the ACCA of the clipping of the range of serial numbers.
My guess, 1925 Light Delivery. The 6R-2013 could be 6K-2013
