The celebrated Pennypacker horse collar was a specialty of the Fox River Horse Collar Manufacturing Co., which claimed that the general mechanical construction of this collar “has rendered it the best device of its kind known to the trade. It is so constructed that the draught is close to the horse’s neck instead of back on his shoulders, and thus an easy and comfortable fit is effected.” Their goods were widely known, from Pennsylvania, Ohio and Virginia on the east, to Kansas, Nebraska and Missouri on the west. They used about forty tons of rye straw yearly for filling horse-collars, and the hides of about 2,000 head of cattle were required yearly to supply them with leather. The Seamless Team Collar was a standard pattern, always on hand. They also advertised their willingness to make any grade or pattern to order on short notice. Their collars were for sale by any harness dealer in Ottawa and elsewhere. In 1883 the factory had a capacity of turning out 300 dozen collars per month, which were shipped throughout all of the western states and into many of the eastern states, and even, in 1886, to Sydney, Australia.
