I have some points from a archeological survey conducted in 1977- they are UTM typereferences and appear to be the right length for 10 metre accuracy and accompany the map names such as SE55-10. All good.

I know the actual locations of some of these points and others I do not.

The problem is the references are not valid for current day maps. I've looked at the possibility that they may be AMG66 and need converting to either AMG84 or MGA94 datum, but even these conversions do not yield valid locations.

Now I am not a gun with UTM, preferring to work with Lat Long. My question is, could these references be pre-metric ie in feet or yards? If so how can I convert, other than getting old maps?
