Sorry for the confusion everyone. We are currently restoring the remains of three medium guns: 4.5-inch and two 5.5-inch. We are hoping to end up with one of each caliber. I believe that both the 4.5-inch and the 5.5-inch used identical carriages, the only difference being the barrels. The easiest way to spot the difference at a glance is that the 4.5-inch barrel is longer and obviously not as thick
Any help re parts would be gratefully received.
James.
