I have been wondering for awhile now what the U's were on these. The dimensions on the blue one are 6'' tall by a 5'' diameter. As for the brown one, it is 3.5'' tall and 5.25'' diameter. And what would the value of these be too? Thanks

Update: This has been identified as a U-801, with a value of about $30.00, by several ICON members. Thanks to all who replied!!!
