The 45, 50 and 71A tubes generally come in two bottle styles, the globe which looks kind of like an incandescent light bulb in shape and the "ST" shape which has a more Coke bottle shape to the glass bottle. These tubes can be marked with a 1, 2 or 3 in front of the number (like 145, 245, 345) but this numeric prefix is NOT a consistent determinant of the tube's shape. This is why I have listed either ST or Globe only and not all the numeric prefix variants.
We will try to accommodate your wishes with respect to manufacturer. But these tubes are very old and normally in short supply. If we have a particular manufacturer's type, we are happy to send it. If not, we can only send what we have. The used tubes will be tested just like the new ones and will meet or exceed the specifications for the particular tube.
