The rear cover gives the Alma Works in Darlaston address, which
Marlboro bought The Holdsworthy Co Ltd late in 1985 and moved
from Oakfield Rd London to Darlaston, West Midlands soon after.
Their custodianship was short lived as Falcon bought the Holdsworth
& Claud Butler marques in Feb 1987.
So the Darlaston address dates this catalogue between very late
1985 & Jan 1987.
