database for cap numbers?

[Phil Harris]

some may know about my frustrations with cloudy lamps being delivered... well this past week i was looking at the cap numbers and the three clearest grande lamps i have all have the same number on them.  i was shocked because these were NOT purchased at the same time (but were from LL directly).  this makes me wonder if anyone is interested in gathering a list of cap numbers that are known "good" and those that are known "bad".  i suppose there is no useful purpose for it really but could be interesting to see if there is any identifiable trends with born on dates.

I would bet that the same batch of lamps will have the same properties.  The shame is that there is a lack of continuity between batches.  But if someone wants to compile the info I'll contribute my cap codes.
