This is not a Suhl or Haenel stock. It may have been stocked by Mahrholdt-Peterlongo in Innsbruck, Austria. That company apparently bought up several "left over" barreled actions in Suhl in the 1930s, stocked and finished them and sold them as their own product. Here is a photo of a Schmidt & Habermann, Suhl M21 action in 5.6x52R aka .22 Savage HP, completed, marked and sold by them in 1941 (Ferlach proof 9/41)
