Thanks to those responding. Your information has helped me with the decision to buy the gun I described and to determine my offer. Apparently it is not a Brent, but is a very well built, heavy gun. The forend does not have a Deeley push rod, but rather a concealed spring loaded lever in the forend iron that works against a lug beneath the bottom barrel rib. It’s choked .008 and .012. It’s seen use, but had a caretaker along the way.
