Hello All,

Thanks for your reply.

Now that I've determined that its a 577-500 No.2 chambering, all the back and forth banter about measuring the bores isn't necessary.

I'd really like to know the answer to the question: "... What is the meaning of the "stars" stamped on the breech end of the barrels over the chambers?..."

They are located almost exactly at the center of each chamber. They appear to have been stamped "after" the last refinishing / re-blackening based on the raised edges.
