Medal "Participant In The National Revolutionary War In Spain 1936-1939 50 Years".

[CtahhR]

There would be more chance of people within Spain being awarded post-Franco but most of the Spanish Nationalists were dispersed. It is most likely that a Spanish dealer/collector imported this to Spain due to its historical importance to that nation. The open market will cause all sorts of items to travel all over the world and without supporting documentation the best we can do is speculate.
