There appears to be a great deal of pertinent stamps on each tube ahead of the flats near the lower rib. I read the data string to be: "1016.45.D.290.45". I don't see a decimal between the "29.0" but it may be there as it is difficult to see. For some reason that Eagle conjure's up Cap's name. I could easily be mistaken.

Kind Regards,
