Hello!

I am looking to build a plastic model of a u-boat that had the conventional deck gun AND the muli-barrelled anti-aircraft armament in the extended wintegarten.
Did such a sub exist? Or had the deck guns been phased out when the antiaircraft armament was beefed up?
Are there any plastic models out there that depict this? Failing that, are there any u-boatplastic models that have the heavy flakvierling with shield?
Great website!
