I would consider getting them scanned, but I have no idea where or how
much is costs and I had a camera to hand! I tripod would have helped,
but I was keen to get on with it.
The plan now is to give the maps to the local records office however I
though I would investigate getting the scanned first - or possibly the
records office has a suitable scanner. I do know that Steve Chilton
has access to one, but then there is the problem of getting them there
and there might also be a charge of course.
