I also have a Holdsworth with the very same decals (which could mean nothing) but mine is early to mid 70s and a friend has an 80s holdsworth that does not have the gold circle decal but I'm also not sure when 531st reared its head mine is just 531DB
also early 50s/60s I believe) holdsworths used a actual head badge and 70s ones seemed to just use the decal type badge
