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.
Model names:
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
