This auction (ending in two hours)
...has three tubes clearly marked "NL-54362". According the amazing Alan Franzman site (on the Wayback Machine) this tube should have top and bottom symbols and the B-54364 is the side-by-side version. I have B-54364s and they are in fact side-by-side so what's the deal here?
I'd love to have the top and bottom version. Any idea what the correct number is for that one?
