Hello Forum,

Can anyone give me an idea of the age of these vintage keys (Masterlock, and Chicago lock Co.)?
Thanks for looking!

The Lion logo on you Masterlock key started in '31 and the end date isn't so clear, but appears to be used into the '60's. Looks all brass with out a nickel-silver coating, so probably to the later part of that date range. Talking in general terms and anyone is welcome to slap me down on this.
