Good Bye Night Latch, Hello Deadbolt

Finally found the name for this old part to my door.  It's called a night latch, not a deadbolt.  That color is called champaign.  So there's that.  

Night Latch.  They all seem to look alike:

Here is a second one I found at eBay.

And a 3rd from eBay.  Similar design.  Only features are designed slightly different. 

And one more from eBay . . . .

Glad I got a deadbolt instead.
