It's hard to see in the picture, but my oscillator is labelled:
Freq 5.000 MHz
Notice the same '0410-2540' line. So you're probably right. I wouldn't
be surprised to find that Lucent had multiple sources for the oscillator
and their part number for the oscillator was 0410-2540.
By the way, mine is working. Frequency looks good - still moving, of
course. Tuning range is good. I've got something like 200 Hz range on
the EFC. Current drain is good at about 70 ma. I found a broken
ferrite wirewound inductor on the oscillator board. I have no idea what
the value is so I just had to throw in something to get it to work. My
selection criteria was entirely scientific - magnetic core, lots of
turns, and present in my junkbox! That may explain why the output level
is only -5 dBm. I'll ovbiously have to revisit that.
