Times sure have changed, price-wise. My 20 Sterlingworth with DT and AE, ad 28" tubes, is an early Utica gun- i bought it well used for $600 Cash money. Just for the hey of it, do either of these 20 Sterlingworths have ejectors. Always figured that feature added about 20% to the base price of the gun with extractors.
I learned many years ago to never leave empty ejected shells in any grouse covert- whether public lands, or private farms. A "tell tale" remainder of some hunting activity there-- RWTF
