Dear HTC, hereby requesting addition of larger drop tanks for Spitfire XIV.
In Aces High, we have the 30 imperial gallon (36 US gallon) drop tank. It turns out the Spit 14 had several drop tanks available, the 30, 45, 50, and 90 imperial gallon models (so 36, 54, 60, and 108 US gallons).
This link is the Spit 14 pilot manual. Relevant information is on page 41, Section 66, Part c, "Long-range fuel capacities" that lists the drop tanks available.

Searching books.google.com on "spitfire xiv 90 gal" gives various references such as:
The Lord is My Shepherd, by Wilkinson (pilot of Spit 14's in 41 Squadron), p. 43:
"In September of 1944 our 41 Squadron was finally equipped with my beloved Spitfire XIV's and we were assigned to high altitude Lancaster bomber escort. The long distance flights to the Ruhr district and other targets in Germany with a 90 gallon belly tanks were exciting events recurring often. . . ."
and p. 47
"With a 90-gallon belly tank we could fly for three hours."

"The the five blades of his Spitfire XIV suddenly windmilled to a stop. . . . He closed down the throttle, then reached down to the awkwardly placed fuel noodles . . . to switch off the 90-gallon drop tanks and go to the main. . . ."

"Owing to its short range, it was considered that the Spitfire XIV would tend to be operated with a 90-gallon long-range tank. . . ."
