Why don't 109s have these?
 

Why don't late model 109s have their air to air morters like so.....

I've set them up on a 190 for 200m and 3 sec. delay and they are a lot of fun to try and master :)

I doubt many late models found any use for the 21cm mortor in the last 6 months of the war as they were too busy trying to avoid swarms of allied fighters over German airspace. I have not seen any photos of K models with them but that does not mean they were never used. I suspect someone can dig up late war photos with some ??

Well I ment G6's and later.
