Lot of (2) Flexible Hydraulic Hose Guides that accept two parallel 3/4" OD hoses and allows hose flex but prevents kinking or tangling in tight bend installations.  These guides can be bent to ~180 degrees in a 9 1/2" wide space - see pics.  The segments can un-bend to ~90 degrees of curvature; they do NOT straighten out flat/straight.

Overall ~12" long  x  2 1/2" wide

I do not see any manufacturers markings, these are factory surplus where mostly Parker hydraulic components were used.  New old stock.

Probably used in some articulated machinery, could also be cool cosplay, hacker, or steampunk components!  Brand new!
