(lever)(noimage)(research) Slaymaker purchased Trenton Lock and Hardware Co. in 1905. After the purchase Slaymaker manufactured some of the Trenton Scroll locks making some mechanism changes (Locking bolt and shackle spring). We have not been able to identify any Scroll locks manufactured by Slaymaker between 1893 and 1905. There are a couple of Scroll locks that we have listed as being manufactured by Trenton, but in fact could have been manufactured by Slaymaker. This subject requires further research ... 2018.
