These sliders say for 2.5.1922 but are sliders that specific? All my older m2.5 sliders are working just fine for landscape on 1922 so why not just say for m2.5? Do these in particular not work on older versions of manila but older sliders still work on new manila? Anyways, found some others for anyone interested:
