It's hard to see in the picture, but my oscillator is labelled:
0410-2540
Model OCXO107-10
Freq 5.000 MHz
S/N 6396-40
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.

The photo looks like one of the 2 units I have but the info on
one if my oscillators says:
CTS Knights
970-2074-0
5 Mhz
0410-2540
8947
I'm pretty sure the last numbers are the
date code. If more than one company made these units they
could have been in some piece of equipment made under military
contact where they required a second source and/or spares.
