Knight MK-85 50 and 54 cal

[10acres]

I recently acquired two Knight MK-85’s, one in 54cal and one in 50cal. I guess there is a special tool to take out the breech plugs. Looks like a slot in the middle of the plug that can be accessed after the nipple is removed. Also, where can I find new breech plugs that can be removed with a socket.
