Gun Stuck Closed

[John Helms]

My wife inherited her grandfather’s Parker. According to the S/N search it is a 1905. The original damascus barrels were replaced by Parker in the 60s (we have the originals) with modern steel barrels.
Right now, it is stuck closed. The top lever is off center to the right and will move further to the right but will not go far enough to break the gun open. The safety was stuck in the fire position but by manipulating it and wiggling the aft trigger, I got it to move to the safe position.
Does anyone have any ideas to get the gun open? I am very familiar with guns but new to Parkers and don’t want to damage it.
I have attached pictures to show the position of the top lever and of the receiver.
