The last pictures Andy, got me pondering on something I had thought about when looking at my Leyland parts list.
Namely, underpans, or undershields (Leyland parlance) - were they a requirement of the extant law (either police regulations in London, or county traffic commissioners); or was it common practice to fit them due to the oily/leak-prone designs of the day; or further was it because of the mixed traffic of horse and lorry that demanded no drips of oil onto pavements? I wonder when they stopped fitting them, and does anyone know?
