"Push Key 6-Lever Brass Round Padlocks (Pancake) - Diamond"

Most of the padlocks in this category have 3 Arm Levers.

The 1900 Slaymaker-Barry Catalog shows a 2 inch diameter model. I have not seen any of these padlocks.

"PAT 1892"  is stamped on the reverse of the shackle. There is no 1892 patent so I am going to assume that this is an error. Mfg by: Slaymaker-Barry Co. William F. Troast Patent # 536844.  (D-450).
