It is fun to look through an array of sporting magazines from the late 1940's and early 1950's, they are chalk full of adds for WWII surplus. You can find many interesting listings. I think almost everything in that add from posy #79 was WWII surplus. Usually, antique shops have these types of magazines, I've bough a fait amount over the years that have adds of interest. Often they are only a buck or two.
Something to always keep in mind was that going into 1945 industry was starting to transition back to making goods for the commercial market. Raw materials was in such large abundance coupled with lifting of restrictions on their use. Industry began to really ramp up as the war in Europe began to wind down. As early as the start of 1945, materials were being surplused through the War Assets Administration, being sold publicly. Before VJ-Day, hundreds of contracts were being cancelled daily. Some companies went back to business as usual, some began marketing new products based off of advancements of technologies developed for the war effort. Some actually still continued to produce the same products under government contract but marketed them commercially, those that weren't under copyright or classified. Many of these cancellations of contracts were sudden, leaving tons of raw materials in various states of completion. In the case of this shovel, likely the spade blanks were stamped and ready for assembly but following the cancellation, they were not assembled and sold at scrap metal prices. By the spring and summer of 1945, the WAA was quite busy liquidating tens of thousands of tons of material. Supply depots were filled to the brim on both coasts and in May 1945 troops were slated to come from Europe. There, that equipment sat. Same for the west coast. Cataloged and potentially some ear marked to supply the pending invasion of Japan. As that theater came to an end, deliveries were routed to liquidation centers all in their original crates, sold for pennies on the dollar. Many early entrepreneurs of surplus, on the west coast, made their purchases from auctions at depots in San Francisco. Trucks loaded to the brim. One could only imagine crates as far as the eye could see of gear.
The best representation is to look at civilian publications. Much of their content was very much "war" related from 1942-44. Then compare the content to that being provided in 1945 printings, you hardly see any reference to the war or at least greatly reduced. All adds and commentary was getting back to Life without war, especially after VE-Day.
