I'm not sure of the grade,the wood is a very definate upgrade with a darker diamond inlay at the wrist just in front of the checkering,it has full scroll type engraving on the rec and trigger guard and a very nice pigeon engraved on the rib.At this point the most I really know about greeners is that I like them.I have another 16ga made in 1890 that is in beautiful condition,a hammer trap gun converted to a 45-90 double rifle,a minature club gun in 22 cal that is just about mint and a martini greener conversion to 22 cal.
