FK.51

[Dali101]

Greetings to local aircraft experts.

I have a request and a question.
Is it possible that there were single-seat FK.51 fighters in the SCW? Dali

As memo serves ten single seaters of the FK.51 were delived to the Spain in 1937.

I know the article ...

But it is very exceptional and there is no mention of these single-seater FK.51 anywhere else.
Would they bear the designation FK.51 bis?

I am preparing materials for a future strategy game from the SCW period.
I'll be happy to find any help on the local forum, thank you.
