Need Service number of two OCs from 430 Squadron
 

Good night to all!
I tried hard to find out the service number of two O.C.s from 430 Squadron ( RCAF ) but got no joy. PLEASE, could someone help me with the service number and full name of:
a) S/L Frank H Chesters, DFC
b) S/L Jack Watts, DFC
I found the other OC´s name as being S/L Cal Davis Bricker, DFC and got his service number, but the first two are lacking on my researches.
Many thanks for welcomed help and the full name of Chesters ( sometimes written as Cheaters on some sites...)
Yours
Adriano Baumgartner
