Can anyone identify where this photograph was taken?
Who? We know this is D C S Bassett.
What? We know this is HRG HLO 163, now owned by Nigel Brown.
When? We know the photograph was taken on the 1950 Lands End Trial (8th April 1950).
Where? Surely someone can identify those very distinctive gates?
With thanks to Nigel Brown for supplying the photograph which is reproduced
