From the estate of author, fishing guru, and winner of the Buz Buszek award, Andre Puyans:

For sale here is a vintage "Arnold" fly reel by Bivans Mfg. Made in Los Angeles, Ca. Produced in the 60's and 70's, the Arnold reel is a neat piece from fly fishing history. The reel is in excellent condition with only minor signs of handling. The Arnold reel features anti-reverse handle, LHW or RHW, and is quite durable. The reel had many capabilities that were fairly advanced for it's day. Included in the pictures are scans of the original manual, these help a great deal in letting the owner understand and appreciate how this classic reel works. Line weight: 5-7wt. Reel weighs 7.30 oz. Diameter 3 1/4"
