Imperial Metal Products .22 Caliber Pistol: Identification & Value

Question
I have a 22 cal pistol that I am trying to find out when it was made and the value of the gun. On the barrel has 22 cal model IMP also, on the gun has Imperial Metal Prod,Inc. NYC USA

Answer
I can find no listing anywhere for this gun. Sorry! Even tried cross-referencing it to no avail. As far as value, without any further details, as long as it is functional, I would say $100.-150., as most any pistol that works is worth that if it is nice to look at.
