What is the age and value of a Dan Wesson Arms model 744 44 magnum revolver?

Here is advice and input: * The pistol pack which I bought in the late '70s, also included four different barrels, tools and two grips in a fitted case. The current value of one of these pistol pack seems to be between $500 and $800 with an near perfect example going out at over a $1,000. An individual pistol might be from $300 to $500 a depending on the condition. * See www.gunbroker.com, or www.Gunsamerica.com for what other people are doing with them. * At 100% it's $375.00; add 20.00 for heavey barrel disc. in 1995.
