No worries Jim. Seeing the frame is devoid of any Belgian marks, I'd guess it was sourced inland in Bohemia. Sometimes there is a monogram on the standing breech and if there isn't anything there, then you will have to inspect the frame with 1/2 pipe side-frame reinforcement in & out. If it was sourced from the Weipert area, Emil Gustav Rupert Bittner & Winzel Morgenstern are 2 of the prime culprits. Let me look

Kind Regards,
