It's a brand from a French or Russian F1?

Hi, I wanted to ask if anyone is familiar with this manufacturer? Could it be a French or Russian F1? It had some bluish-gray paint on it, so could it be French.

thank you!!

Hola. Por si sirve de ayuda, tengo una carrocería de F1 con las mismas marcas, de la Guerra Civil Española, importada de Polonia.

Thanks! Besos! I searched on this website https://armamentoguerracivil.com/granada-de-mano-polaca-wz-23-y-wz-24/ but I didn't see any of the brands that matched the ones in the drawing... so I ruled out the Polish one. Interesting, a Spanish Civil War and Polish import. Is it listed on any website? Thanks!
