Why you shouldn't buy an old bulb (used or N.O.S.)?
If you were to buy an N.O.S. (new old stock) bulb from a vendor at a swap meet, the going price per bulb would almost equal what we charge for our complete set. And what the vendor doesn't tell you is that when you go to energize your newly purchased N.O.S. bulb, it may instantly burn out, or is certainly destined for a very short life. Obviously. this is also true of bulbs purchased from junk yards.

The reason is simple; these bulbs were not designed to last 40 years. What happens to these bulbs (even never used bulbs) is that over time, they can develop cracks in the varnish (seal) on the back of the bulb. Once a crack develops, air can enter the bulb (which is under a sealed vacuum), and the filament will instantly burn out if power is applied.
