Always good to verify dimensions unless the seller already has. Most of the contents of the tubes in both the cases I bought did not match the number on the cover. But it's so easy to take off three or four covers to look inside, and then get them back on the wrong tubes.
what amazes me is how often a seller will say "it came that way" and not consider that maybe someone else at some point in the life of this item that's around 100 years old - messed with things! Just because it was that way when they bought it (even if it was 50 years ago on something that is 100 years old) that does not mean it came from the factory that way.
