What is the value of a model 19052 bb gun?

I believe you are asking about a Daisy model 799.19052 made for Sears.

If this is information is correct then it's a Daisy Model 1894 with an octagon barrel. It looks very much like a 3030 lever action rifle.

If you want to know the value then state the current condition of the rifle. Give it some sort of rating like. Poor, Fair, Good, Very Good or Excellent. Then I will be able to give you an estimate of value.
