Need help IDing Austrian(?) musketoon(?)

[Patrick Chadwick]

It looks like a Jaegerstutzen. The Dornstutzen has a longer support block beneath the sliding quadrant.

Described in the book "Die Hand- und Faustfeuerwaffen der Habsburgischen Heere" as Variation "B" with the ramrod lying in a slot behind the ramrod pipe.

The lockplate, dated (1)860, confirms that this is a later version. However, the ramrod pipe is mounted further back than on the example shown in the book (dated 1861). Transitional model/upgrade/repair?
