Okay, I know this is a real reach but can anyone provide information That would help get information on six Spad 12 that were in service with the RKKVF in the early 1920s? Ser. # 1545, 1581,1586,1600,1604 and 1609. This info came by way of the French Aircraft of the First WW/ Flying Machines Press. I appreciate your consideration. Cheers!
