Most likely it is an "S", or an "M" Model Commercial Mauser Sporting Rifle. This Model more commonly had the " spoon " bolt handle, however the pear shape handle tends to indicate a commercial spotter.
The 'S' TYPE has a schnable half way doen the foreword, with a schnabel at the muzzle , as opposed to no schnabel on the "M" type , and a metal cap at the muzzle.
The rare range rifle mostly had top wood, an dis unlikely with the barrel length you describe.
These are highly regarded sporters in anyones language, and in the condition you describe should have a retail value of $3000-$5000.
Looking forward to the pics
