I recognised the figure of 152.4mm as equating to 6" as soon as I read it but it is easy to check/convert by dividing 152.4 by 25.4 which gives 6 in this example.

The reason that I suggested naval is because it was a commonly used calibre of gun used on cruisers of the Royal Navy and Commonwealth navies during WW2 and beyond. A good example of this is HMS Belfast, now a museum ship, which was originally part of the "Town class" of cruisers and their main armaments consisted of 12X 6" guns mounted in 4 triple turrets. After hitting a magnetic mine in 1939 and nearly being lost, HMS Belfast was substantially rebuilt into a class of her own (improved), featuring many alterations and improvements but still retaining her main armament of 12X 6" guns that she has to this day.
Thank you for your reply. I did measure it with calipers. There are no markings nor stamping so on the shell. I'm going to study the HMS Belfast now. I love this stuff!
