A ready-made display collection! There are 27 tubes in all. Eight are 6-1/2" long; 10 are 4-1/2" long; and 9 are 3-1/2" in length. [id=397761822] One of the long ones has an incuse "E.P.Co." along the shaft, which I understand to be uncommon. The remaining long ones are unmarked, save for the one that someone wrote JT in pencil on. Eight of the ten medium-length ones have a "G" embossed on the top (?) flange, which I am told is an unattributed marking, and the other two are unmarked. Five of the short ones have the same "G" embossing on the flange, and the other four are unmarked. [id=397761864] The oak wood holder is likely not made for these, but it sure displays them nicely. 8^) A few of the tubes have small rubber bands wrapped around them to hold them steady in the holes. [id=397761910] ADDENDUM: I've cleaned these, and they're all nice and white. The penciled intitals are gone.
