Looks like a poor copy of a Lloyd Instruments tensile tester, twin ball-screw driven crosshead supported by bent sheet-metal outers, the gripping fixtures look poor as well, and the Z type load cell is just old hat these days. Worked for Lloyd's ~30 years ago, made redundant when Ametek bought and asset stripped them. Got a 3m tall Instron where I work now for 'small' stuff, the big testing machine hall goes up to 20m and 30,000 Tonne's!
