1/ @cal11 : the hands on your pic are not for 7806 imho . You can see the so called "bloody hand" in 1974 catalog posted by Fred , rep.D , and 7806 , center of your own pic ;
2/ square tip hands as used on late 7806 = 1806 hands
3/ according JM Lesmala -
http://www.lesmala.net/navitimer , square tip hands were also used by Breitling service on 7806
4/ luminous material on sharp end hands is yellow for Venus 178 versions and green for 7740 - cal 11 versions . It is noticeable on pics and very clear on real pieces
5/ last point that I just realize today by looking at Fred's catalog : rep.B is not a 1806 but a 816 encasing a Venus 178, so we can find 2 versions of square tip hands , 145-95 and 180-100 holes => not impossible to find square tip hands serviced on 806-809 versions
