I have a drilling (three barrel, 12 x 12 x 9.3x7.2) with Manhattan Arms Company stamped on the lockplates. Has fine 29 1/2-in damascus barrels, Italian walnut stock, external hammers, top lever, and sidelever that opens the breech. Locks up tight like a bank vault. Light scroll work, excellent workmanship. A close look at the proof marks tells you it was made by JP Sauer and Sohns in Germany with a serial number that dates it at 1883. On the ebony buttplate is the initials (logo) for Schoverling, Gales & Daly. This firm imported firearms from Europe at the Chamber Street address in New York. In the past few years I've seen a few Manhattan Arms Company shotguns (hammerless) at the local antique gun shows.
By the way, the stock is about 2 inches short for a proper fit (about 13 inch LOP). Does anyone know a decent gunsmith in the Detroit-metro area where I can look into a wood extension. Tried a add-on pad, still too short.
Thanks,
