I long ago forgot why I ever bought these tubes. Maybe Visoflex? Maybe macro? Maybe G.A.S.? Most likely! In any case, as you can see, the larger tube is an OTSRO code. The smaller tubes are both 16471J tubes. In any case, let's say that a $15 donation to APUG will make all three of them your very own. Buyer pays actual shipping. Enjoy!

Thanks,
