Gracie wroteCan any one tell me what year Eagle Lock Terryville CT opened and closed their shop in Ohio? I have H. Gerstner & Sons machinist tool box made in Dayton Ohio I am trying to date. The key is from Eagle Lock Co. with the numbers A50M5 which is the box number.
The Eagle Lock Co. was formed in 1854 and closed in June, 1975. They were located in Terryville, CT that entire time and to my knowledge they never had a shop in Ohio. You might send an image of your tool box to Gerstner & Sons at the link, they have been in business since 1906. They may also be able to tell you the years that they used the Eagle A50M1 thru A50M48 key series.
