Welcome Valentin. Looks to be an early Westley Richard's toplever design. Is there an APUN or use number associated with the Brevete stamp? Also could you post an image of the Brevete stamp as well as the underside of the tubeset where there might be a "Crown" over "GR" or possibly some Belgian proofmarks. Last is there a crossbolt thru the doll's head extension?

Kind Regards,

Raimey
