It has come to my attention that there was no such thing as the 700B Narrow spool model (only the 600B was a narrow spool model). Although you can plainly see that this is a narrow spool reel it could be that the side plates have been switched from the original ones. I purchased this reel as is…so I am not completely sure if this reel is "as original" or not. If you have information on whether the narrow spool model was only made in the 600B model then please drop me an email. Thanks!
