Nothing for now but I'll sleep on it. It was brought to my attention that it also has sideclips. There really wasn't anything short about this longarm. 8 pin sidelock, stocked to the fences(interesting article in the DGJ on fences), etc. I think the "N" in the square like boundary pairs with the 1962 datastring stamp. It would have represented the semi-smokeless and the 4th proof. Here's yet another guess: let's say the components were sourced and the work up too the "in the white' state was subed to the craftsmen in Suhl post 1912 & pre-1923. Then the gun just sat until post June 1st, 1940 when German was in control of the Weipert proofhouse. Then then stamp of the falling fir tree with the crossed hammers atop would only denote the Weipert proofhouse and not the mark noting the longarm being exposed to the 2nd proof firing. That would explain it being on both flats, as per the German rules, and the absence of the stamp of the double headed eagle with a "3" on the breastplate, which would hold the position on the underside of the right tube along with the absence of the preliminary data string. Once again very nice Lovena example with Lovely Poldi( Krasna Poldi ) tubes. I forgot to note the typical Weipert "beetle" type safety. As far as I know Weipert still has their records.
Kind Regards,
