Sewing Machines working or not hand or electric (Hugglescote LE67)

I have been forced into early retirement and have started repairing sewing machines and rehoming them to keep me occupied. I'm an eex electronics and electromechanical engineer so need to keep my mind and hands occupied. Hand machines are serviced and sent via a local Rotary club to disaster areas and areas without electricity supplies. I can collect anywhere thank you
