Hello Robert,

you can find a suitable circuit in my 1979 publication in the VHF 
Communication magazine "Design of crystal oscillator circuits".
A free download of the paper is available on the AXTAL website 
www.axtal.com under Technical Notes /  Technical Articles and 
Publications. The paper is lsited at the bottom of the table.

Best regards
