Republican Spanish AF Marking Question

[Bryan H.]

What does the "CM-xxx" serial number stand for?  Were there any other numbering systems on Rep. Spanish aircraft?  Most Republican Spanish aircraft had them, so I think it might be some sort of sequential system; like USN/USMC BuNos.  If I'm putting them on a MiG-17, how fictitious can I get and still have an "air" of believability?

Thanks in advance for you help.

Just a SWAG, but "C" could stand for "Caza" (Fighter).  Dunno otherwise.

MANUEL!!!

Hi Bryan,
    You can try this for Spanish Civil War numbers and codes and this for General Spanish Civil War aircraft info.

I hope this helps!

Thanks!     So...  It looks like "CM" for Caza MiG would be entirely reasonable & I can make up the number part!
