What about compared to a Model 28-2?
The Model 28 was I believe parkerized and may have had a fixed rear sight. It was marketed as a working gun compared to it's upmarket brother, the Model 27.
You have a chance to get a very very nice revolver!!!!!!! $5-700.00 depending on how good it is and how bad you want it. No matter what you end up paying, you will be happy with it.
