I had some information in my RAILWAY PASS & GUIDE magazine published in in 1989
1888 - 1890 S.R. Slaymaker?
1890 - July 2, 1894 Slaymaker, Barry & Co
July 3, 1894 - 1900 Slaymaker Barry Co sold out to The Baldwin Automobile Manufacturing Co
In 1900 Samual R. Slaymaker purchased the original Lancaster property and went back in business
1900 - October 23, 1907 S.R. Slaymaker
October 24, 1907 - February 24, 1917 Slaymaker Lock Manufacturing Corp. (company dissolved)
In 1917 SR Slaymaker and WE Fraim formed a new company
1917 -1921 Slaymaker Lock Co in 1921 WE Fraim bought out SR Slaymaker
1921 - 1929?? Fraim-Slaymaker Co
not sure of the 1929 endpoint and Slaymaker came back in the picture and the company lasted until 1986
