Gogor, Asken who make these guns

Often when I look at some Spanish guns webside like MIL ANUNCIOS I see guns on offer with the name ASKEN and GOGOR.
Before I ask this question I also want to investigate and find out who make them but I am still without result.
I am sure that I find answers to my questions here.

Marc,

Asken was also a famous American Military Attache to Spain and a gun writer in the USA (Col Charles Asken). Col Asken was a good friend of Sr. Aranzabal of AyA. I am a friend of Col Asken's son and he told me that in reviewing his father's papers that he had found information regarding the use of the Asken name for a gun model.

This may be the case for the FSC (Felix Sarasqueta) gun.

Thank you both this is great info, I remember the link and I have seen pictures of Col Askins special order gun on this forum.
A 10 gauge isen't it ??
