How do you remove the door handle?

[muna0001]

Hey all,
first time I am posting here. My wife and I bought and restored a 1976 Sovereign and we never received a front door key when we bought it because it came from a farm field in the middle of Wisconsin.

I'm trying to remove the lock and handle plate so I can bring it to a locksmith and see if they can originate a key for me, but I can't get the inside handle off. Does anyone have any ideas on how to do it? The bottom screw on the handle is gone so Im not sure what's holding it in place but I can't pull it off. Any help would be greatly appreciated!
