Taking the "trash" out Gun lock?

[mangum]

I always go through the "trash" i find and make sure i don't miss anything. These were my "other" finds from this weekends hunt. A lot if it may be junk but the one iron piece looks a lot like the lock off a gun. I looked at the brass piece again and it is marked Telechron inc. Ashland Mass, turns out it's an electric clock motor so no help needed with that. Thanks & HH!
