Modifying the gun barrels

I did some adjustments on the provided gun barrels,
Luckily i have some good connections to a lathe, the prototype is now a much better match when comparing them with the gun barrels on the lower
decks..

But during positioning of the gun carriage I found out that I have made the gun carriage slightly too high.
underneath some pictures of the gun carriage in position ..

..maybe changing the size of the wheels will do the trick..
