Record Office: Look up needed at Kew for New Zealand based researcher

Hi, I am desperately seeking someone who is going to Kew to look up a 1748 document for me. Not sure what it is written on or what script might need interpreting, so might need photographing. If anyone can do this, please contact Peter direct *email address removed* and I will send details

Thanks in advance

Peter
