Model 25 "Hornet" bolt/barrel ?

Bolt head question.
Is the bolt head for the Model 25 "Hornet" like the Model 10? Meaning, is the extractor in the bolt head?
Anybody got a picture of the case area of the bolt head? Front shell pocket? (Pictures would be worth 1000 words!)
Saw the bolt brakedown but no front view of the bolt head case pocket.
The rim of the case fits under the extractor plate? Is there any "reinforcement" around the case just above the rim in the bolt head?
Barrel questions.
Is the chamber end of the barrel flat like the 10 or is the end of the barrel stepped into the bolt head?
Questions are related to chambering a Model 10 to a "rimmed" 20 VT, Hornet, etc. Thanks in advance for any provided info, Mike.
