P-47 Thunderbolt - "Brisbane" tanks

I am looking for some good photographs of the 200 gal "Brisbane" tank produced by the Ford Motor Company in Brisbane, Australia. These tanks were designed by 5th Air Force engineers to be used with the P-47Ds flown by the  348thFG.  As these early flat keel D-2 und D-3 Thunderbolt models did not had the provisions for external drop tanks they had to be modified to carry them. I am also looking for photographs of the keel and the belly shackles of these modified P-47s.
Can anyone help me out?

Many thanks in advance and Best Regards,
Christoph

Chris.........I'm afraid I couldn't find a good clear picture but this shows the 4-point attachment on them ; the tank is similar to the 150 gal. flat tank used by the Eighth-Ninth AF in Europe.
I think they were designed by Fifth Service Command and made in Brisbane. Colour was neutral grey.   Nick
                                      

When fitted they had a rectangular sheet metal plate on each side for extra support on rough fields in N. Guinea , they probably also helped the tank to clear the tail when released ; they were angled slightly outwards .
This is 42-8077 no. 12 of the 340FS.                    Nick

Nick, many thanks for your help!

I have seen these sheet metal plates from the second photograph also on other, later P-47s in the PTO. They were even used together with the tear drop shaped 75 gal tanks. Was this some sort of "in the field" modification or something like that?

Chris    I'm sure this was a field-addition in the Pacific and CBI; the tanks in the ETO and MTO usually had spring-loaded metal braces for support.
The plates apparently weren't confined to the 348th as they can be seen on 81FG P-47s  in China and 58FG on Okinawa.
The 15FG sometimes had them on their P-51 wing tanks and (earlier) on their P-40s underwing bomb-racks in the Central Pacific ( but the P-40s were plywood ).

Nick, thanks again for your help. I have another question, perhaps a little bit off topic here. The early P-47s (-Cs and early -Ds) in the ETO had the B-7 shackles retrofitted at the air depots in England (not sure of this modification could have also been made at unit level). The 8th AF had the same "range problem" as the 5th AF - why were no B-7 kits shipped to the SWPA? Was it a matter of theater priority?

Chris         this research  were done by VIII AF Air Technical Section at Bovingdon, and the B-7 shackles were fitted at group level beginning with the 4th and 56th FGs. The modification was from a 4-point (the 75gal. metal tanks were originally for P-39s and P-40s ) to a 2-point on the P-47.
From the D-6-RE they were fitted as standard on the production line (with 2 sway-braces on each side ).
The P-47C and very early Ds had a 200-gal. flush-fitting plastic / paper belly tank as a temporary measure (not really effective ).
The 75 gal. tanks were shipped over from July 1943 as there were not enough 108 gal. locally-made paper ones available, by about Dec. the situation had improved and deliveries of 75s was cancelled. By about May 1944 most had been used up and the paper (and some 108 gal. steel ) tanks were standard on both P-47 and P-51.
It seems the 348th was left to devise it's own solution, and they came up with the 200 gal. flat tank ( I think they got some similar 150 gal. ones from the States). They were in action from June-July 1943 at the time the 75s were allocated to the UK ; though some would arrive in the Pacific and China later.                 Nick
 

Nick, you were of great help for me! Thanks.
