The Ordnance Survey list has 4 Benchmarks in grid SE1948, all of which are normal Cut Marks

1 – CUT MARK – HIGHER CARR FM HO SE FACE E ANG
FOUND IN GOOD CONDITION
The Cut mark is on the South East face of Higher Carr Farm House, on the East corner
There is a large hedge between Higher Carr farm house and the road, probably grown as a light screen to stop the car headlights shining into the windows. Fortunately there is a gateway cut into the hedge which allowed me to just get enough of an angle to see and photograph the benchmark

2 – CUT MARK – GT P 44.0M NW JUNC SW SIDE NEWALL CARR RD
MISSING
The Cut mark is on a gate post on the South West side of Newall Carr Road, 44.0mtrs north west of the Junction
It’s not quite clear what junction the description is talking about, I’m guessing the wall junction, but anyway that is rather irrelevant. The gate has been replaces with a more grand entrance (so you can get your vehicle off the main road before getting out to open the gate) and thus the gate post with the benchmark on is long gone

3 – CUT MARK – STO GT P SW SIDE RD NE FACE
MISSING
The Cut mark is on the North East side of a stone gate post on the South West side of the road
As farms got more mechanised the machinery used got bigger and gates needed to be widened to allow access to the fields. The stone gate posts on this field entrance have both been replaced by wooden ones and the benchmarks lost

4 – CUT MARK – GT P 1.7M SE HEDGE JUNC SW SIDE NEWALL CARR RD
MISSING
The Cut mark is on a gatepost on the South West side of Newall Carr Road, 1.7mtrs south east of the hedge junction
Again the gate has been replaced and the old stone gateposts replaced with wooden ones – though the more southerly one is still present, lying broken and buried in the field, though from the measurement it was the northern one that the benchmark was on
