I own this gun that was done by Chic Worthing. Maurice Ottmar only chambered the gun but I believe Chic had input from Maurice, it certainly has a Germanic style. Chic stops by here from time to time, perhaps he'll comment further
It's a G33/40 in .338-06.
"The following firearm is a German style open sight rifle built on a G33/40 action. It has an old commercial German take off barrel, that was rebored to .338 by Cliff Labounty of Maple Falls, Washington. Maurice Ottmar chambered the barrel in .338/06. The barrel is a half round/half octagon with a full length rib with an integral hold down on the barrel and an integral sling swivel stud. The stock is Bastogne Walnut from Don Cantwell, Chico CA. I shaped it with raised side panels that are more evident in the second picture. There is a metal escutcheon on the forearm with a captured wedge that holds the barrel. I rust blued the metal. One of the most interesting features is the Lyman 35 sight. They mount on the bolt stop and swing out with the stop. They are a marvel of the machinist's art. Lyman sold them in 1900 for $12, but to put that in perspective, the Winchester 1890 22 rimfire sold at that time for $16. These sights now sell for $350 and up."
