Black and Decker GT350 electric hedge trimmer (Ebley GL5)

Trusty old electric corded hedge trimmer. Started to slow down when tackling my giant hedge last June. It may have just been overheating after running for hours in the summer sun, or the motor may need some TLC. I confess I bought a new one and never gave it a second try. It was still running when I last used it, albeit slower than I wanted. Worth a punt for a smaller hedge or bush? Or to be refurbished or used for parts by someone technologically minded?
