This is my 38 pounder naval gun. I actually made this model quite some time ago but the original had a ridiculous 1945 constructions in the blueprint due to having to make cylinders the hard way. If you got anywhere near it, your frames would plummet into the single digits. It was a mess, so I never uploaded it. I replaced all of those laggy things with logs and got it down to a svelte 74 constructions and it causes no lag whatsoever. Great for all of your naval (ore even navel) battles. There is also a black circle in .png format which you can use on the muzzle to simulate the bore.
