This device appears to be a T65-1, which is the plastic-cased successor to the leather-cased T-65 [1]. There are no markings indicating the type, make, or year on the device itself. However, a very similar model found on Chinese auction sites apparently carries the designation "HCX-3". The plastic casing seems to draw some design inspiration from the German FFsp 33, while the overall construction bears similarities to the U.S. EE-8 field telephone.
It is a simple, compact, lightweight, and durable design, the handset feels somewhat flimsy though, reminiscent of a toy phone.
