No
I believe you have a JC Higgins model 101.1 This should be a single shot 12 ga. It was made by Savage as the Savage model 94. They were made between 1926 and 1945
50-150 USD or so
Your shot gun was made By Harrington & Richardson For J C Higgins -Sears / High standard. in 1945 http://www.histandard.info/PDF/Sears%20Shotguns.pdf
gunpartscorp website has a cross reference to find the originial make and model, and usually his firing pins.
What is the value of a Stevens model 940b 16 gauge single shot? And when was it made?

No. Different models
Bluegrass 12 gauge shot gun model 1900
16 gauge, 2 and 3/4 inch, any shot from fine birdshot to buckshot.
You can, but, it will cause a slight bulge in the barrel.
