Schaft differences

[yamoon]

20131208_205611 (800x600).jpgHello
I have studied the drawings in vol3 of Tom Rowe's Alte Scheibenwaffen. I don't see the differences between a Tyrolerschaft & a Wienerschaft. I have a Franz Sodia System Von Schatzl martini I have always assumed it was a Tyrolerschaft, but now I am not sure. The rifle is quite large, Meffert take down system, barrel is 1 inch at the muzzle, 30 inches long, rifle's weight is 16 lbs. Can any one shed some light on the differences?

The design you show there is always referred to as "Tyrolerschaft" in all of the catalogs and references I have, and denotes the large, dished cheek-piece in this style.
