On the Mongoose Traveller forum CT The Traveller Adventure, p44 was cited as a source document for collapsible tanks, external/internal demountable tanks, and new information on drop tanks.

Demountable tanks only, and the publication date is 1983.

I've checked my copies of the Traveller and Periodical Bibliographies and have not been able find the title. The text cited appears to be the same as what is in CT Adventure 5 TCS.

TCS has all the options. With a publication date in 1981.

Can anyone please help me figure out what book is being cited?

I didn't do a search of either Book 5 or the relevant jTas issues, but I know at least drop tanks are a fairly early addition.
