I recently acquired a US dollar signed by nineteen men and women, most of whom were OSS operatives in Burma, Thailand, and China. At least two were associated with the American 1stAir Commandos. On the back of the dollar are the signatures of three men I believe to be RAF or RCAF squadron/flight leaders working with British SOE Force 136. There is the signature of James Blackburn. I suspect he is the same James Blackburn who commanded 159 Squadron and was awarded the DSO for his work for Force 136. There is also the signature of Les (Leslie?) Brookes, who could be the leader of 628 Squadron. This squadron also worked with Force 136 and Brookes was piloting one of the Catalina Flying Boats landing operatives during "Operation Oatmeal." The third signature is Tommy Lee. I believe he is the Canadian Tommy Lee who was a flight leader in 357 Squadron. "B" Flight of this squadron (Catalinas) became 628 Squadron and also worked with Force 136. The American officer who owned the dollar was Major Frederick J. Roehs of the Army Air Corps. I have not been able to find much on him but one newspaper article from March 1944 states he was "a member of the staff of the general commanding the China-Burma-India Theater of Operation." I do not know which general (Stillwell, Sultan, Mountbatten?) or what staff position. However, it certainly had him in close contact with the OSS and SOE. Do any of the forum members have access to log books or documents that might include the signatures of these three RAF men? I feel this will be the only definitive way to be sure I have identified the signers correctly. Thanks for any assistance.
