It's got to be hard to get a reply when you are competing with a hot RM thread. I almost hate to bring this up, but did you measure the barrel from the front of the cylinder or from the front of the frame? The difference is about 1 inch. I say I hate to bring it up because you may already know this and I would rather not insult your intelligence. It is a mistake a lot of people make though. The barrel length could change the value estimates.
