Second hand

I've been searching Den. It looks like all the Wadleigh's on here are 1930 models with 9AF movements. None of my parts cross-reference books list parts for a 9AF movement. It looks like the 9AF movements were only used from 1929-1931 and they must not have been used in very many Bulova watch models. I would imagine this is going to require measuring the staff for the seconds hand and searching for a generic hand that will fit the staff. But that's just my 2 cents.
