Ranger, thats a great site,I hadnt been to it for some time now.
Started looking around on it and found a cool pic of a K4 with a 20mm gondie located where the DT goes.
You can find it in the section that covers german guns,MG151/15 and MG151/20,in the archives section.
I've seen this type of istallation before but never on a single engine A/C,it was syncro'd and fired through propeller arc.
Wish I could read german as there's a ton of great documents to be found on that site.
