Garrison Cannons similar to the Cannon in 17519, but "fatter" to upgrade the gun size. The 17519 scales at 60 MM to a 12-pounder, 8.25 foot length (3.3 inches from muzzle to Base Ring, do not include the Cascable or Button). Barrel diameter at the Vent was a very good match for the 12-pounder. It is a wonderfully done piece. I would sell the cannons as a single pieces. You could add more detail to the gun if desired, but I do like the 17519 cannon. No manufacturer is offering a garrison cannon (Ship Cannon, Pirate Cannon, Fort Cannon). Gun carriage in the 17519 is very nice, so I would keep that element, just "fatten" as needed.
I would lean towards offering a 32-Pounder and the 18-pounder.
Barrel from Muzzle to Base Ring (60MM Scale); Vent Diameter at 60MM Scale (inches);
4 pdr. 2.2 - 2.4 inch Barrel, Barrel Diameter at Vent 0.37 inches.
6 pdr. 2.4 - 3.6; 0.43
9 pdr. 3.2 - 3.6; 0.49
12 pdr. 3.2 - 3.6; 0.54
18 pdr. 3.6 - 3.8; 0.62
24 pdr. 3.6 - 4.0; 0.68
32 Pdr. 3.8 - 4.0; 0.75
Just keep the proportions the same as in 17519, with the diameter of the barrel at the vent changing. I would vary the barrel lengths. Base Ring from Table below might be helpful as it the widest dimension to compare.
I have no idea if this will work, but going to try ....... rivet counter information for 7 guns from a 4 pounder to a 32 pounder.
The forum does not seem to like Excel Tabs, so awkward table below - but dimension at 60 MM Scale (4 inches = 10 feet). From Muzzle Moving Backward.

Table Does Not Work, looks Great Before I hit the submit/save button, but with patience usable.
