[volt-nuts] Voltage references on phone base station

Just found something interesting.
On my old salvaged 2G base station (don't ask!) I
found a chip which looks a lot like a REF02 and from memory this
is indeed a precision IC.
Can these be salvaged and put to use? I found them on greedbay but
due to my chronic cashflow problem will have to wait a bit before buying
For my purposes (boo hiss!) 4SD is fine ie 1.0186 volts
Although for the sheer heck of it I might ovenize the chip(s) and make a proper temperature compensated "Weston" source.
My current meter seems accurate despite being inexpensive, its a pink one purchased on promotion from MUG.
However it does deteriorate if the battery is low hence a need for a reliable
voltage standard to go with my atomic clock (see above)
