Impossible to answer without a detailed description of ALL markings, condition, box, accessories, paperwork
These were made between the years 1978-1985.
I can say that the stevens model 9478 shotgun was made during the years 1978-1985.
The Stevens 9478 and the Stevens 94K are both single-shot shotguns, but their barrels are not interchangeable. The 9478 has a unique design and specifications that differ from the 94K. Therefore, it is unlikely that a barrel from a Stevens 9478 will fit a Stevens 94K. Always consult a gunsmith or firearms expert for specific compatibility questions.
A breakdown of the parts for a Stevens Savage Arms Model 9478 is found in the book The Gun Digest Book of Firearms Assembly/Disassembly Part V - Shotgun. It has exploded views of the stock and its availability on the market.

Your stevens model 9478 shotgun was made during the years 1978-1985.while serial numbers were on the shotguns I do not believe that serial number records were kept as to the year of production.
value of Stevens model 94 long tom perfect condition
50-300 USD depending on condition
50-125 USD
it depends on the model...........
50-160 or so
my be 1000000 $ or 5000000 $ or 10000000 $ Maybe, but you'll sell it a lot quicker if you only ask for what it's worth. $25 if only good as a parts gun, $75 if in nearly-new condition. If it's 100% like new, you might find someone willing to pay over $100.
