I volunteer on a ship in Bristol harbour called the SS Great Britain. I can give a talk on the designer of the ship Isambard Brunel, and the changing world in which he lived in the 18oo's. I am prepared to give talks within Bristol and nearby towns or villages. I have a usb stick to use in your laptop, projector and screen to show powerpoint, or to plug in to a TV . I am prepared to talk at short notice.
