Clayws has acquired yet another interesting example utilizing a square hidden crossbolt with "J.P. Sauer & Sohne" on the tubes and W. Eblen of Stuttgart on the top rib. The preliminary marks on the tubes are German and the final proofmarks of 1920(#133) are of the Weipert proofhouse. So was W. Eblen of Stuttgart and others like G. Wilcke, Heinrich Scherping, etc. actually agents of Sauer & Sohne???














The engraving strikes me as being similar or the same as that found on Frantisek Faukner's examples.
