the guns were made by the same makers. the way of making a naval cannon is
the same as making a land cannon.

From recoil mechauism to trunnion design and placement to providsion of
systems to blow compressed air through the bore naval guns and land-based
artillery are quite different. Then there are the carriages, as different
as day and night. After all those, there's the corrosion problems facing
naval guns


a gun that can be used at sea can be used on land and vice versa.

Provide a few examples (and don't use the mounting of T34-76 turrets of
river and littoral gunboats as one of them, 'cuz it didn't work well enough
to qualify). Modern naval guns require rapid train and elevation to meet
stableization and other fire control needs. With the exception of tank
guns, land artillery does not require that capacity. With the exception of
tank guns and land-based AA, naval guns tend to be flatter shooting (higher
velocities) than land guns. Naval guns, fixed in place, can be much heavier
than their land-based counterparts, the reason that smaller 18th/19th
century naval guns, 2 to 9 pounders, were longer barreled than their land
conterparts, designed to be drug quickly about by horses. It was however
quite common to employ larger naval guns as "siege artillery", fixed in
place.

the tertiary battery on german warships was the same 88 that was used on
land for AA and AT.

Aside from sharing the same bore diameter and projectile/case dimensions,
there are few common parts and components to the two systems/guns.
88mm/90mm wasa popular bore diameter, essentially 3.5", the largest fixed
round which experience dictated could be handled easily in confined
quarters. The sturdy English ratings were expected to hurl 4" rounds about
like ping-pong balls, and manhandle 4.7" rounds equally well (and the old
land 4.7" howitizer was quite different). The USN adopted the semi-fixed
5"/38 for easy shell handling


the 3inch gun carried by M10 tank destroyers was the same 3inch gun the
navy
used


Your "common" list remains pretty short (and the trunnion placement on the
3" naval version is quite different, higher so that the naval gun can be
elevated for AA use).

How about a list of 105mm naval guns? 127/128mm/5" land arty?
