TM51,
Wow! That's a blast from the past...XERB, the Mighty 1090! I used to listen to the Wolfman from my suburban bedroom in Orinda Calif in 69-71...sorta like nearly meeting the outside world...and through my shortwave listening, on a Lafayette Radio 5 band receiver from a kit, $40!, I sent a QSL to Radio Havana Cuba, and promptly got on their mailing list for their 'Granma' newsprint propaganda sheet...complete with copious stories and BW photos of Che Guevara; my mum was a bit worried, but the CIA never came calling... Thanks for the memory, cheers

What are those tubes hanging down from the airship?
Surprisingly, this compilation...
https://bluejacket.com/usn_avi_lta.html
indicates that the the earliest classes of Navy dirigibles (A, B, C) were filled with hydrogen. It wasn't until C-7 that helium was used.
I suspect the smaller of the two tubes was used to spill the water ballast so the ship could rise. The other tube might be a gas vent for descending. Maybe that tube is a fill tube. In either case, why the strange angle?
I think that they are tubes to allow air in and out of the "ballonets" (interior balloons) to control the pressure in the airship:

The ballonets within the airship also control the trim.
I do not see any rigging on the angled one there might be something on the smaller one.
