The Weipert stamp is the leaning/falling fir tree in an escutcheon/shield surmounted by crossed iron clubs or flails just below the Crown over W. Typically this represents the 2nd pass for a tube thru the Weipert proof facility say till 1927-1928. So let me revise my guess on the date. I'm not sure of the exact date of occupation(some time in 1938??), but Germany was in control of the proof facilities in the Sudeten Protectorate by 1939. Prague's proofmarks were recognized but I don't believe Weipert's were. Only the Escutcheon/Shield with the Leaning/Falling Fir Tree surmounted by crossed iron clubs or flails was allowed to denote which German controlled proof facility thru which the sporting weapon passed. What is missing is the 2nd Imperial Eagle along with an encircled 16 noting 65mm chambers. On face value it would seem that the marks are mixed regarding the proof facilities. But closer inspection would say that some mechanic in Weipert married a Belgian Krupp steel serialized tubeset to a frame and sent it thru the Weipert proof facility sometime between the original occupation of the facility by the Germans up till the mandatory June 1st, 1940 new proof law.

I'm curious what those numbers are just ahead of the flats.
Why there isn't a final pass datastring or datecode as we know it, I cannot say.
Kind Regards,
