Count as an old gasbag (8)
I believe the answer is:
zeppelin
This clue might be a double definition.
'count' is the first definition.
(I've seen this before)
'an old gasbag' is the second definition.
'zeppelin' can be an answer for 'gasbag' (airship). I am not sure about the 'an old' bit.
'as' is the link.
Can you help me to learn more?
(Other definitions for zeppelin that I've seen before include "German invention" , "Cigar-shaped airship" , "German inventor, designer of the first rigid motorised airship, d. 1917" , "old gas-bag" , "one of the earliest air-ships" .)
