Matt Amt brought a reconstruction of segmentata slides that replaces the leather. It is from the Gamla publication from Dec 2014, though the finds were back in 1989.
Where is it exactly in the publication? Read it, maybe I've missed it, but definitely did not find it...
page 66-68 "The Armor of L. Magus"
relevant paragraph:

"Oxidized remains of the internal leathers are visible on the faces of several plate fragments. The near complete section of the back-plates of L. Magus’ armor is of particular interest. Bishop notes that “one of the weaknesses of the Corbridge type of armor was the use of three overlapping back-plates and modifications were evidently made” (Bishop 2002:43). He further notes that “modern reconstructions of the Corbridge armor are also prone to this same problem.” Indeed, the order of the back-plates of the Gamla specimen is reversed (Fig. 4.8:11b, 11c), similarly to the back-plate fragment from Corbridge (Cuirass 5; Bishop 2002: Fig. 5.13). Moreover, a unique sliding loop device was observed on the inner side of the large fragment of three back-plates that replaced some of the internal leather straps, the rivets of which are still visible. The three plates had four oval iron rings on their back face, 51 mm long and 22 mm wide. The flat rings, 2 mm thick, slid upon the flat rivets’ shanks. The flat circular heads of these rivets were 12–14 mm in diameter (Fig. 4.8:11c). The principal device comprised two loops and three rivets. Each loop was attached to two rivets, which in turn were fastened to two different plates (the upper and bottom back-plates). Every pair of loops was attached to a rivet that was fastened to the third, middle, back-plate. The central rivet, which had two sliding loops attached, formed a constraint upon movement of the triple plates, whose maximum dimensions were 15–20 mm. No parallel has yet been attested to this device in the Roman world, which may indicate that the Gamla specimen was a local innovation. Sliding mechanisms are found on medieval suits, an example of which is seen on the armor thought to have belonged to Wladislas, King of Bohemia (c. 1510 CE), in the Wallace Collection, London; Bishop 2002:81, 93; and pers. comm.)."
For anyone who hasn't seen it, Guy Steibel's presentation in London (now on Youtube) recently features some discussion of the Gamla finds, with some colour photos of the slides and rivets, among other things:
