Came across a nice 2"mortar No2 tail fin at a show the other day but marked FD 1945 with the tail cap 11/44. I have a No4 tail on a para illum dated 10/43, I thought by 1945 with No4s in full swing that the No 2 would be faized out then, any one know when the last No2 tails were last made. What's the latest dates on your No2 tails.
