Do you know what load they are cut for? That osc is for overtone operation
and those usually run the crystal in series mode.

If he doesn't care about absolute accuracy, series or parallel mode is not
a concern. The LC tank will reduce phase noise, but shouldn't have a Q of
more than about 10-20. If you tune the tank for max amplitude, you are sure
to be at the right operating point for the xtal.
