I acquired this image via ebay a couple years back (location not known to me*). I have included a rather large scan here for the consideration of others. Given that I am replicating fruit packing operations, it provides me with lots of context and fodder for modeling. I am not a car or truck expert, but I place it somewhere in the early 1950s if I had to guess**.
There are several details that stand out to me. First, the variety of vehicles, both in terms of types and ages, is interesting and worth noting when selecting vehicles to add to such a scene. I am also interested by the layout of the main packing structure. It appears that the then current loading dock was added after the main structure had already been in use, and was an add-on as operations grew. By main structure, I am referring to the facade with "VALLEY FRUIT CO." emblazoned in red as well as the rest of the structure behind that facade. The even newer addition at far right could be replicated as part of an even larger scale model operation (note that it appears that this business handled tomatoes and possibly other fruits and vegetables, as well.)
The whole scene is worth consideration as a modeling subject for anyone needing such a facility on their layout. I suspect that the Walthers Valley Citrus Packers would be a good kit to use as a starting point to kitbash this, along with some scratchbuilding or kitbashing with other models. Enjoy!
