HI Andy,
I researched Abels file year agon in Korlinemuster Aachen.
It is not very well preserved, but some early data are present. At first, yes it is the same person who served with KG 3 and later was shot down as StaKa 5/KG 51 on March 2, 1945. About his fate see mine forthcomming book about 2. march 1945 airbattle...:

What can I write u now is as follows:
----------------------
Hptm. Friedrich Wilhelm August Abel, born on 28.November 1919 at Wintenberg/ Westfallen.
After pilot training flew with III. and IV./ KG 3 over England. Later become a staffelkapitän of 4./ KG 3. Has been twice wounded. When in January 1944 III./ KG 3 become II./ KG 51, Lt. Abel was with the Group. Pilots slowly changed their Ju 88s for Me 410 for a while and later starter to fly Me 262. Abel was shot over Nijmegen, Holland on March 2, 1945 while flying Me 262 A-2a W.Nr. 110553 (9K+EN).
