The most-used example in my custody is an E17 that had an accident in the hands of a previous owner, and had the barrels lopped to 28 inches, resulting in absolute cylinder-bore tubes.
It was offered at auction in Melbourne, and reasoning that no Victorian would want an eight-pound quail gun, I tossed up an insultingly low bid and won the Greener!
It is perfect for shooting non-toxic shells at the local goose swamps, throwing a surprisingly even pattern of No.2 steel to 35 yds or so.
Never seem to have any trouble getting my limit if the birds are flighting well.

Just discovered that one of my other Empire Greeners is also a 1951 build, serial numbered only 77 apart from the new acquisition!
Apparently 17,268 Empire guns were made between 1910 and 1965, so there's plenty of them out there.
