RAF Harrowbeer information board, similar sign to that seen on the 17th October 2012 walk around the Common and the airfield except for the map being oriented the other way round (top-to-bottom) because we are on the opposite side of the airfield here ..... the airfield was built for fighters during WW2 when Plymouth became a target for German bombers .....

Roborough Rock - the 'dry' one as opposed to The Rock Inn, Yelverton. Also known as Udal Tor, Ullestor and Hurlestone Rock (1765). It is a metamorphic rock, being a magnesium limestone. 'Proper' limestone is calcium carbonate (CaCO3). Magnesium limestone is calcium magnesium carbonate (CaMg(CO3)2) and compares with "dolomite". "Roborough stone" has been cut from dykes across Roborough Common and used in churches e.g. Tamerton Foliot, Plympton and Shaugh Prior; it has a warm colour, no sparkle and becomes pitted. An example is probably the nearby Queen Victoria Diamond Jubilee monument (a few photos below).
Another view of Roborough Rock showing the proximity of the remains of the remains of the Allan Williams turret, this was a simple anti-aircraft system using converted .303 machine guns or similar. Allan Williams is hyphenated on some web sites, but the designer was actually one A.H. Williams.
The basal ring of the Allan Williams turret
A drinking fountain erected to mark the Diamond Jubilee of Queen Victoria .....
There were workmen parked by this monument today so here are two photographs from 28 November 2012 .....

Beneath the brambles ..... towards the camera, the lower left quarter of the photograph shows the drainage channel that brings drainage water from the old airfield .....
The small road bridge (almost opposite the Crapstone turn-off) over Devonport Leat. The drainage water runs about 200 metres to go under this bridge and then is piped (almost centre of the photograph) to the nearby Plymouth Leat .....
Plymouth Leat, showing the inflow from Devonport Leat: movies of these water movements were made on 21 December 2012, during a period of heavy rains.
Inserted from 28 November 2012 .....

From the same position, looking towards Plymouth along the top of the tunnel, which is in a cutting.
Devonport Leat is lined in places, usually near small bridges, with granite sleepers taken from the P&DR which was nearby.
Clapper bridge, the golf course is to the right.

Road bridge at SX 51475 64706 on Roborough Down Lane, unusually with worked granite, which runs to Lower Upperton and beyond. It was under this bridge that a dismembered, burnt body was found in 2001: BBC News - Link 1, BBC News - Link 2, BBC News - Link 3, BBC News - Link 4, BBC News - Link 5 - the bridge is now known to some as "Dead Man's Bridge".
Dartmoor ponies standing with their rear quarters against the wind, sheltering behind gorse.
Mistake? A parallel trench, perhaps the leat builders made a mistake that was corrected here.

Houses / farm seen along the way.
A plethora of points - in a kissing gate, where the post and struts are made from bent railway rails. Having discovered the origin of the "kissing" aspect, I am disappointed, no need to "pucker up" ever again! The etymology of the name is that the gate merely "kisses" (touches) the enclosure either side, rather than needing to be securely latched - and I thought it was all to do with good old fashioned philematology!
Another tunnel back through the railway embankment.
A look at the now-dry cascade down from the breach in Plymouth Leat .....
The now-dry Clearbrook Leat.
