NW9, Kingsbury Road, Roe Green Park
On our visit in 2019 we could see neither the stone nor the blue plaque. Since they cannot be seen we've marked them as lost. Information welcomed.
When we visited the building was a children's nursery, so one couldn't get close but, 2021, it is apparently home to Kingsbury Veterans' Club so another visit might be in order.
We wondered why Baird chose this building so, thinking he might have required maximum elevation, we checked the topographic map, but this area is not particularly high or low. Perhaps the building was just available.
