I recently scored some old Austron 5MHz oscillators at a military surplus store. They were listed at $10 each. (The price may have gone lower after I BSed with the owner for a while) One is a Sulzer model 1120N from 1972. The other is a Sulzer model 1150C from 1971. That 5 MHz oscillator has serial #5, which is kind of neat. Both work and are very stable.
