The help - Hirtenberger factory

Can someone specify period of production in Austrian Hirtenberger factoy, when they used in head stamp letter H with dot behind? ( " H. " )

This topic has come up before without an answer being given: mannlicher-h-headstamp

As a starting point, I know of military style cases with 1905 (and evidently 1906) dates without the dot but with the dot from 1907 - admittedly the formats are different.
