For anyone in the market for an inexpensive property marked 1906 Navy, here's one for you. This current GB listing has that "been there, done that" look and appears legit to me. (I have no connection or knowledge of, the seller other than messaging him for the serial number (it's #7037, a new listing).
For those looking for barrel serial halos, the first 10,000 or so 1906 Navies (the no-suffix bloc), do not show halos as they were serial numbered prior to bluing, however, the property marking was stamped after the gun left the factory and it does have visible halos.
The gun is missing a magazine but the price, so far, seems like a bargain.

P.S. Ignore the "Commercial" in the headline, the seller doesn't know what he's talking about.
