Do you have one? If so a photo would be useful. The name rings a bell in some way but have you any idea about the date of the frame? This might help to trace adverts etc.
EDIT - a quick Google threw up what I had suspected. DS frames came from Chevin Cycles in Otley, built Jim Hargreaves who also built the Pavone frames for Peacocks in Halifax. Allegedly, Lloyds may have transfers for them.
