This 501 was the last and perhaps finest of a great series of metal 500 series half-encapsulated spinning reels which made continual minor advances over 20 years.
More general material covering the whole 500 series is here.
They were followed by the less accepted plastic models 601 and 601M and 602 while the 501 and 506 were still in production in 1983. The two remaining metal models 501 and 506, were gone from the Tight Lines catalog by 1984.
Please be patient and enjoy as they appear and do contribute!
If you have any others not listed above, that are unneeded or doubles in your collection and are available for a reasonable fee, I would be very pleased to hear from you.
