From this image I am fairly sure that these rifles are actually breech loading:
You can see the trapdoor style opening breech
If so, I believe they could be Wänzl rifles. Also, I think that this rifle may be a Werndl–Holub with the barrel cut back to the stock:
Lastly, I beleive that the other rifles currently listed as Gewehr 1871/84s are carbine variants of the Werndl, like this one --commando552 (talk) 11:20, 24 March 2017 (EDT)
