I would be surprised to learn that forend was supplied by Parker Bros. as it does not have the reinforcing rod threaded from the front of the forend into the forend iron.

Not a bad gun for a gift. I wouldn't turn it away.
However, it has surely been restocked. The look of the comb is not right at all and the checkering does not look right either. The forend is some sort of creation for sure. Being how rough the inletting is on the inside of the forend, I would say that it is nowhere near original or factory.
One ejector is tripped. Might also be part to do with the difficulty of reinstalling the forend.
I do find it interesting that the forend latch does not have the points on each end of it. Maybe removed by the party that made the forend?
