The side mills are the first coffee mills patented by Charles Parker. Those mills were made of cast-iron with sheet metal hoppers, mounted on a wooden back, very similar to Increase Wilson mills (patented back in 1818).
Parker No 0-3 are the first models. The only difference between those were the size. Between 1850’s through the 1890’s produced the Union Side Mill series. (No. 10, 15, 20, 30)
Another variation of wood back mills appeared around 1860’s. The series was called the Eagle Side Mills. (No. 50, 60, 70, 80, 90, and 100)
