First 12 size maximus was model 1894. 1901 sample here. Also here is 1919 slightly smaller 10 size. Uncommon and a superb high quality accurate piece. Someone special ordered with the enamel decoration. These small ones are rarer and initially listed for higher $ than the popular 16 size sold at the same time as their best production grades. Note the diamond end stones used in the Maximus.Competitors: 920, 922 Hamilton; 190 Lord Elgin.
