Those D.Fraser bolt actions on pre – 98 Mauser actions I have seen so far are all built on the Chilean and Boer war M95 action, not on the Swedish 94 (carbine) – 96 (rifle) action used on the Husqvarna sporters. Important details allowing identification are visible in the photos of the ".360 Fraser" offered by Hallowell. The boer war Mausers did not have the upright protusion on the cocking piece nor the narrow bolt guide rib of the Swedish and 98 actions, but a small rectangular "safety" lug on the receiver, just behind the bolt handle. They also had a much shallower "thumbhole" cutout in the left receiver wall. Besides adding a typical bolt handle, Fraser did a lot of file work on the bottom metal before stocking the action: The front end was wasp waisted and the triggerguard filed to a Scottish style. Otherwise, the magazine of the Fraser looks normal for a 95 Mauser.
BTW, the barrel of one of my own Oberndorf commercial B 98 Mausers in 9.3x62 (not a Fraser) is also marked with an imperial designation, .366.
The service load for the rimmed/flanged .360 NE 2 1/4" was a 300 gr bullet in front of 30, not 35 gr cordite!
