20mm Flakzwilling question

[Cybermat47]

Just wondering, was the 20mm Flakzwilling ever fitted to VII B, VII C, and/or IX C U-boats, specifically in 1941? In SHIII + GWX and SH5 it's possible to do so, and I especially trust the research of the GWX team, but I was wondering if there's any photographic evidence.

As far as I know, no VIIB was ever fitted with the flakzwilling because I don't think any VIIBs were ever upgraded to the wintergarden type conning tower. I don't think any other U-boats got the wintergarden with the heavy flak mount until 1943.

True, but the 20mm Flakzwilling would fit on the standard conning tower, as it was a light flak gun.

Just to be clear, I'm talking about the 20mm twin, not the 37mm twin or 20mm quad.

I thought you were talking about the quad 20mm. Then yes by late 1941 in SH3 at least the twin 20 becomes available.

I know, I was asking if anyone had photographs of U-boats with Flakzwillings in 1941.
