''chuck adams'' was a house name of samuel (sol) assael (''john spencer'')'s john spencer & co. and of the badger books (& quite possibly of his blazing westerns & lariat westerns imprints, too - i've not checked), used inter alia on work by john s. glasby and sometimes by e. c. tubb.
this badger books imprint p/b looks from its cat# as though it represents the disappearance of the blazing westerns imprint back into the badger books imprint.
