i've seen one german sabre with this double ring scabbard,but it don't think the germans liked them much.
the uk's 1908 looks very much like the 1913 'patton' us army sabre, with very slight differences, mostly in the blade, i suspect the '08 must have influenced patton a bit.
just for interest, here is a 1861P British HAC Light Cavalry officer's sword -with the ubiquitous double ring top mount. (HAC = Honourable Artillery Company)
