To be fair they should not. I have noted a lot of them are made with #2 weight barrels which are rather heavy. The ealry J spring fore ends tend to not stay on well. I have three and find them all well made. One is almost 8 pounds and is too heavy to carry when the gun room is full of seven pounders which I would rather carry instead.
Perhaps it is just the Parker like hinge pin does not appeals to buyers. From a mechanical viewpoint they are just like a Sterlingworth of later production with the possible exception of the fore end attachment system.
