for information the FB has been repositioned and cleaned up but not moved from its location, I have photos of the original position taken when the rendering fell off and the new brick faced wall where it is now sited, my previous comment related to the accuracy of the height AOD not its location, as an aside as part of my research for a lecture to SAHAAS (the local history society), I was looking for another cut BM along the same building? which I could not locate!

The site has changed since my last visit. The FB is obvious on the new wall a few m SE of the original position. There is new render on the E face of the building where I assume it was located.

FB now repositioned on face of new brick facing and cleaned up in very good condition but not sure if level has been maintained.
It would appear thet the stated level of 395ft is in error and is more likley to be 295ft as it is higher than FB1275(@279ft) and below FB1277 (@344ft).
Also a cut mark just around the corner in Branch road is given at 287.7ft on the 1898 OS map which is still there. On the same map a cut mark level is shown as 296.7ft very close to the FB but appears to be lost (rendered over?).

I thought I had found something on the SE face of the E angle, where the render/mortar is incomplete, partly behind some conduit. But the 1:2500 map shows it on the NE face, E angle. So I'm unsure - I suspect I might have found some rough brickwork?
