Yes, a Baker patent ejector. I'm trying to diagnose this from photos. I think the legs or rods that are attached to the plates that either eject or extract the cartridges are too long. These legs pass through the lump and cock the ejector hammers as the gun is closed. The too long legs seem to be pushing the ejector hammers past the cocking position and further compressing the springs in the ejector boxes you see attached under your forend iron. This tension is released when you push your top lever to release the bolts. This tension is also putting a strain on your forend loop as it is pushing the forend away from the knuckle.
