I've been following this thread for a while. I don't recall if this has been mentioned upthread but, thought I'd throw this out there.
The Gun Control Act of 1968 mandated that all firearms manufactured for sale in the United States must have a serial number ("S/N"). Prior to that, manufacturers were not require to put a serial number on the firearm.
I did a little searching and it's very hard to positively state which manufacturers did or did not include a S/N prior to 1968. The
AI overview from Google states:

So, as
@Richard states,
IF the make, model & S/N are available, it could be a big clue as to what happened.
Good point regarding serial numbers prior to the 1968 Gun Control Act.
Before that federal requirement, use of serial numbers varied from one maker to another. Often the cheaper models of shotguns and
.22 rifles did not have them, while the more expensive ones did.
Many of the major firearms manufacturers would make similar guns for other companies or distributors, stamping them with other trade or brand names.
Such companies as Sears, Montgomery Wards, Western Auto, and others all sold hunting shotguns with their own brand names on them, which were made by Stevens, Mossberg, Marlin, Winchester, and others. Some had serial numbers, some didn't.
Even in 1965, firearms manufacturers and distributors kept records of sales. An example would be the 1963 tracing of Lee Harvey Oswald's gun purchases - cited as evidence against him by the Warren Commission.
If the shotgun Dickie borrowed from Roger Schultz had a known make, model, and serial number - it might have been sold at some time in the last 60 years, and records of that sale would exist.
The solution could be in such details. I think, unfortunately, that this started out as a missing person case and remained only that until it went cold and forgotten.
In 1965, a major effort was put into searching the fields and river, rather than in carefully questioning people, or in reclassifying the case as a possible homicide.
