P-51b being converted to FIRST P-51d -Want pics of cockpit or Inglewood factory assembly of: 43-12102

Hi Folks-- Merry Christmas and Happy Holidays to all! I'm running out of ideas to locate photos (if there are any) of the P-51b that N.A.A. cut-down & recontoured the back of the fuselage- added the 'bubble' canopy etc. There are four photos of this aircraft in flight that I've seen-- but that's all. I've got my new JLC razor-saw ready to --hold on to your hats-- whack two Tamiya kits- P-51b & P-51d-- but would also like to get an idea of what was being modified in the cockpit. Best I can tell from the 4-in-flight photos-- the radio deck looks -51d to me--but don't know if they added the fuel tank there? -if they changed anything or lots on the cockpit walls?? --or if it was left decidedly -51b inside?? I'm pretty well loaded up with DeHavilland Mosquito information as that is my first love to read about and model-- would be happy to share. Best regards-- Dean - Lee's Summit, MO. 'Deanomosquito'
