This is the insulator that I found today in the $2 bucket. At first I thought it had several cracks, but I was instead looking at streaks of milk. It has some damage, but I had to take it home with me. I will take more pictures as I clean this baby up. As you can see from the picture, this is not a MLOD. It may be a new listing for the book. Okay Bill Meier pointed out to me that this looks more like the CD 738. It is 3-3/4" x 4-1/8" so could be the CD 738. Either way, it is not a MLOD.
