Need help to identify a 12bh7a tube

Any ideas about who made this baby? Labeled as a Wards Super Airline, yellow printing, short black plates (size of a 50's GE gray plate), copper posts, D getter. Plates appear to be made from a single piece of metal and are folded and tab closed on one side only. On the non tab side you can see the post through 2 slots in the end of the plate. Silver 12BH7A printed near top of tube with a straight line of 6 dots above it. Yellow 357 over 948 printed on side of tube. Thanks.
