Heavy Artillery, 320mm shells (n-scale)

Single turret artillery pieces not enough 'omph' for you? Perhaps you are just wanting to lob a few shells further than the average artillery commander or perhaps even shell the English coast from France? Heck, maybe you just want the biggest rail mounted artillery piece your network can handle? Inspired by the 220mm ~ 320mm naval guns that were modified for railway usage, this beast weighs in at a massive shell sizing of 320mm across the bore. It is shorter in barrel length to allow mounting upon the standardised ToW system, the shorter barrel has been rumored to produce some in-accuracy over the longer distance, but when your lobbing 320mm shells then near enough is good enough for WWII. Note: This piece is designed to match with the 'Low profile support platform' main body.
