RAF Speke (Liverpool, England) USAAF Liaison

Hello mates,  I am the newest, newby to be known!
I am seeking information about RAF Speke (Liverpool) and the assembly of USAAF aircraft there.  Specifically, was there a USAAF liaison office there and who was stationed there for purposes of overseeing the assembly process.  Any information would be a good starting point.  Thanks lads!  Cheers!  -Dixon Cannon
