The 1250A is a fine clean-up oscillator. As you get into LPN and ULPN quartz like the 1250A it is really an art form with some of the exact same items substantially out performing others. With a unit like the 1250A it could be good to great. It would be a huge improvement in close in Phase Noise vs an LPRO alone, but may not be much better PN the a GPS with a 10811. Some others may have more insight but I would say the Austron 11XX's oscillators are generally a step up from the 10811, but both can have widely varied specs. With standards that age replacement of key caps could be required. I would go for it if you do not have another disciplined quartz oscillator you will have fun with it.
