This set of replacement barrels for the 1/200 scale Mikasa. It includes 4 305mm (12”), 14 152mm (6”), 20 76mm (3”) and 12 47mm (1.85” Hotchkiss Guns). The 305mm and 152mm barrels are machined from aluminum and the other 2 are machined from brass. The 305mm barrels include brass trunnions.
These are designed for Merit International IJN Pre-Dreadnought Battleship Mikasa.
The 305mm is a straight replacement. The machining is quite good, and the only difference is that the plastic piece has what appears to be a cover on the end of the barrel while the metal barrel is bored out to depict the barrel in action.
The rest of the barrels requires surgery to remove part of the old barrel and drilling out a locating hole for the replacement barrel to slip into.
