As it appears this is a custom gun, built from Schilling, Simson Parts, Krupp best steel tubes, what model of the major Suhl players would it most resemble or be patterned after ( equivalent to?)Heym mo. 4,5?, Sauer mo. 40, 45 ? ( did Sauer make any with side plates?) Simson mo._______?

Does the engraving style point to Kolb?

Did Strempel have his own favored style or build that he was identified with?
