Have a 12 and 20 O/U both imported by VL&D. Both condidered very high end back in the day and at the time was priced equivalent to a new automobile....or so I was informed by Griffin & Howe. From a quality perspective, my opinion is quite high on Greifelt. Hard to compare to the other known Suhl firms such as as Simson, Sauer, Sempert Kreighoff, Merkel as they also crafted field grade to super high end arms as well. All that I have seen (pre-war) are of excellent quality internally and externally.
