Are there any reference guides showing photos and giving the dates used by various canning companies? You know, high bead, low bead, no bead, etc. With all the relidded cans out there, it would be nice to see what lids should be on all original cans.

That would be handy ? The only one I have seen has been in the front of the Vol. 2 book and that's just for Tabs. And its kind of generic when it comes to the year.
