Fiat CR-32 production batches

[spanienflieger]

Hello everybody

I am researching about the Italian Fiat CR-32's that were sent to Spain during the vicious Spanish Civil War. I have located several C/n's of those aircraft (usually painted on the tail), and a chart with the different production batches and military registrations (Matricola Militare, MM). Here is a summarized version of the chart:

Type MM Production Qty C/N (?)
CR 32 2589-2870 mar-34/feb-36 282 ¿1-282?
CR 32bis 2957-3239 apr-36/jul-37 283 ¿283-565?
CR 32ter 3420-3569 jul-37/dic-37 150 ¿566-715?
CR 32quater 3892-4667 jan-38/may-39 337 ¿716-1052?


Unfortunately, manufacturing sequence and c/n's seem not to match. For example, aircraft with c/n 101x were sent to Spain in 1938, but according to the production batches those aircraft should have been manufactured in 1939. On the other hand, c/n 451 was captured in september, 1936, but according to the production batches that aircraft should have been manufactured in 1937.

Could anybody help me matching Matricola Militare with c/n's of this aircraft?

Thanks in advance
