      Hi Chris, Many thanks for your contact. Currently, we do not have any more images of LST-531. Perhaps any visitors to the website who have images of the LST’s would get in touch, as we would like to expand our library. I will keep you informed should we have access to more images.
      Thanks again. Steve.
