Here is the N1K1-J George 20mm barrel in 1/32nd scale; this will fit the Revell kit (yes it is old)
But this is just the first offering for AC; i feel you guys need the same service as i offer the ship guys
I do have a min of 4 barrels ordered to make it worth my while
I will not make barrels ican not drill to scale; because these would be just brass sticks; i don't make brass sticks; I make barrels

Pictured here with a AAA sized battery; as you can see detailed and drilled; and the peg at the rear for mounting
email me for more details; FYI; these are just $4 each as they are close to my 1/350th 8" cruiser barrel in length
