Do you recognize this gun

[david lipps]

Sorry this is a bit off topic for parker, but there so much experience here I thought I would check
I can pick up this gun for 50 dollars from a local here
Said the firing pin was taken out by his grandfather so he could keep it in his home and safe... hmmm
They think its a Stevens but they do not know.
The firing pin is lost

Its Nickle plated and they do not even know what gague it is..

Any ideas just from the photo?

Thanks
David
