Hi

Sorry about your father. He left you at least one fine revolver!

The model name is .357 Magnum. At the time your gun was made, they did not have model numbers, but eventually this would become the Model 27.

The barrel is 6" long - it goes all the way to the front of the cylinder.

There are five frame screws, not four. The one in the front of the trigger guard counts.

The serial number puts production in the 1954-55 period.

The value will be relatively high, but I'll leave that to the N frame collectors here on the Forum. I like N frames a lot, but I don't collect them, so others will have a better idea of the price for your fine revolver.
