Not a Parker Brothers gun.

That is not a Parker Bros. frame.

It does seem to be an ejector gun however.

... unless those are cocking rods protruding from the front of the frame knuckle.



.

There was a whole gun very much like that in a local shop about a year ago. It was marked Parker Bros like this one,

According to the Serialization book, Parker Bros. ser. no. 2914 was a L U 0 11 30.

That would be Laminated, Underlifter, 0 options, 11 gauge, 30 inch barrels.



.

That is a crescent.

And, yes, those are cocking rods.

Hammerless sidelock
 

Thank you, Brian. I had never seen a hardware store gun in nice condition.
