This one is a 6 inch Model 28-2 Highway Patrolman. I paid $300 cash on the barrel head for it. It has some finish wear, and a few dings from the original owner having to lay over his motorcycle, and it came out of the holster. The trigger is buttery smooth, it shoots like a dream. If the one you are looking at looks a lot better than this I would pick it up.
Measure the barrel from the front of the forcing cone by the cylinder. I made the mistake of thinking mine was a 5 inch. I am happy with it regardless. I have been shooting the snot out of this one.
Another pick of it next to my Model 67-1
