Difficult to tell from the photo but the modern pot in your second pic appears to be a "miniature" 16mm dia pot designed to fit a 7mm dia mounting hole. If you look for a 24mm dia pot that will be designed to fit a 9.5mm mounting hole and should fit the original hole. The locking tab not lining up should not be a problem, just bend the tab back or break it off on the new pot, as long as the nut is done up tightly it shouldn't work loose.
