i saw this model at ebay its a wm with recording function without the radio, it has autoreverse dolby b, avls i think and it is not bigger than a cassette tape

it stands out from other sony cassette walkman models in design

it has written on the front in bold red letters stereo recorder and it is grey in color dose anyone know which wm model i'm trying to describe

thanks for your help

Would it happen to be a Sony WM-R707?

no it isn't the sony wm-r707, or the wm-rx77
