The WW Greener that I have, serial number 34347 is from 1892. Top of barrel in oval Patent Treble Wedge Fast. On rib St. Mary's Square, Birmingham, England then Winner of all gun Trial 1875-1891.
I'm not sure of the grade either, but looks like a Forester or Empire Grade. Barrels are 27 1/8" and are imp. cyl. and lt. full. Weighs 6 lbs even.
From your writing on barrel compared to mine, your gun was made in 1891
Bore size should be stamped on receiver, mine is stamped 13 meaning .710. But now is .727 and .728.
Also looks like the company moved between 1891 and 1892.
