This is a big stag four blade cattle type pattern in a sportsman configuraton. It has a long pull master clip marked SHEFFIELD CUTLERY , while the smaller blades are marked FOUR ACRE. The bar shield is marked GEO. A. TOWNSEND. I purchased this with a lot of 150 other knives about a decade ago, being the high bidder in a New York state estate auction. I have recently given this to my daughter , it is in excellent condition. She requested I dig up a little history on this knife. Levine gives a listing for Sheffield Cutlery Co-operative Society Limited begining in 1893. However since the knife does not have ENGLAND as country of origin, I believe this is a earlier company or the same unorganized. A search has turned up a four acre nook area near Sheffield, with several bladesmith and filesmiths listed living in the area in the 1840-1860 era. I believe the owner, Townsend purchased the knife during the Civil War years , returning late in the war. I believe the forum members may have a little infomation to add,concerning the FOUR ACRE stamping as this is very unusual and your thoughts are appreciated. Thank You, Rick
