[Johnson] Johnson Valiant Crystal Control Question

[Glen Zook]

For 160 meters the crystal should be "cut" for the
fundamental.  For 75 meters either the fundamental or
1/2 the frequency (cut for a 160 meter frequency). 
For 40 meters the fundamental.  For 20 meters 1/2 of
the frequency.  For 15 meters 1/3 of the frequency. 
For 10 meters 1/4 of the frequency.

After all these years I should know this but the
answer presently escapes me. In order to operate a
Valiant I transmitter on AM using crystals instead of
the VFO, what actual frequencies would the rocks for
75, 40, 20, 15 & 10 meters actually be cut for? 
 
Are they all fundamental frequencies or are some cut
for the 2nd and 3rd harmonics? I'd like to have some
on hand to transmit on, for example, 3885, 3880, 3875,
7290, 14286, etc. Any advice with specific examples
would be appreciated.
